"Putting Industry in the tJWoviEs 

Not All Motion Picture Problems Are Found in Hollywood 

By R. H. Ray 

President, Ray-Bell Films, Inc., St. Paul, Minn. 


W HEN Universal Pictures purchased the now-famous 
"camera crane” which they first used in photographing 
"Broadway.” we all gathered in our plant here in St. 
Paul and looked at the pictures of this crane with somewhat 
mingled emotions. You see, we had just finished making a pic- 
ture in which we used a traveling crane, too . . but what a crane! 

We were making an industrial movie in a big steel mill in 
South Chicago. To make working conditions a bit unusual, we 
had the constant din of more than one thousand riveting ham- 
mers and the clanging of innumerable steel presses. So we had to 
devise a sign language in order to carry on conversation most 
of the time. For hours after the day’s work was done we 
would have a persistent ringing in our ears and suffered from 
deafness. 

And then — someone suggested a few of these "motion pic- 
ture angles” be put in the picture, just for "effect!” 

In the industrial motion picture business we cannot say a 
thing cannot be done. If we did, or if we complained about 
conditions — well, we would not stay in the business very long. 
Like the newsreel men, we must get the picture, regardless of 
weather, lights or anything. So, we decided that a traveling 
crane shot from high up in the mill would give the "effect” 
desired. 

A twenty-ton crane, used for lifting steel, was chosen and 
a huge bucket was hooked onto the big chain hanging down 
from the end of the crane. Several boards were fastened on the 
bucket. These made the platform for the camera and camera- 
man, to say nothing of the assistant who had to hang on like 
a human fly. A few swings of the crane to see if the operator, 
who was fifty-five feet away, would know just what to do. 
Then the Bell ^ Howell was chained to the platform and the 
cameraman and his assistant climbed aboard and away went the 
crane. A half minute later and the scene had been shot. Only 
one "take,” but it was good and gave the desired "effect.” 

Just an example of what the industrial motion picture 
makers have to face in their daily work. Rather a striking con- 


trast to the working conditions in the great studios where prac- 
tically anything in the line of equipment may be had for the 
asking. 

In large industrial plants it is frequently impossible to inter- 
rupt the work of the mill. Certain shots have to be made at 
certain times or you do not get them. If you do not get them 
you lose the job of making industrials for that firm. For 
example, in the same mill mentioned above we had a hard and 
fast shooting scedule because we had to get shots that were offered 
once in about every two weeks. One shot was that of the 
rolling of a certain type of ingot. You have to shoot fast to 
get steel while it is still hot enough to be pliable. No time for a 
director to wonder if the ingot will look better at this or that 
angle. And the heat was terrific. Most of the paint was 
scorched from our lamps, and our cables smoked from the heat. 
Our camera we had to incase in a galvanized iron box. 

The lighting problems of the industrial picture maker are 
often unique, to say the least. A year or so ago while making 
a coal mine picture in Kentucky, we had a crew of three work- 
ing for fourteen consecutive hours in a "cut” of coal where 
the ceiling was only 47 inches high! I wonder if you can 
visualize the working conditions there — the men crawling 
around with the light heads and stands and plugging boxes 
and heavy cable, unable to stand because of the low ceiling! 
No attempt to top light or back light there! 

Frequently we are amused when someone asks us, while we 
are making a factory interior, if the ceiling lights will help any! 
We look very serious, glance up at the eight or ten 75 Watt 
lights and reply: "Thanks, but you may leave them off this 
time.” 

Industrial cinematographers do get some unusual shots in 
their pictures — shots that any cameraman might well be proud 
of. Men in our own organization during the past three years 
have photographed scenes from the following rather strange

fociETY OF 

Cinematographers 

Milner, Miller, Clarke, Arnold and Stull Chosen to Fill Important Offices 


A T THE annual election of officers of the American Society 
^ of Cinematographers, held last month, Hal Mohr was 
chosen as President for the coming year. Other officers elected 
were: Victor Milner, first vice-president: Arthur Miller, second 
vice-president; Charles Clarke, third vice-president; William 
Stull, secretary, and John Arnold was re-elected to the office of 
treasurer. 

The following Board of Governors was also elected: John 
Arnold, John Boyle, Dan Clark, Charles Clarke, Elmer Dyer, 
A1 Gilks, Fred Jackman, Arthur Miller, Victor Milner, Hal 
Mohr, Sol Polito, John F. Seitz, Henry Sharp, William Stull 
and Ned Van Buren. 

On the evening of April 28 these officers were installed at the 
annual dinner of the organization held at the Russian-American 
Art Club, Hollywood. Installation proceedings were conducted 
by the retiring president, John F. Seitz. 

In the selection of Mr. Mohr to take up the reins of head- 
ing the organization, the members feel that they have made a 
wise choice, for Mohr not only is one of the outstanding Cine- 
matographers of the motion picture world, but is one of the best 
liked men in the indus- 
try, always smiling, al- 
ways aggressive, always 
tactful. 

President Mohr has 
had an interesting and 
varied career in the mo- 
tion picture industry. 

Away back in 1906 
Mohr was producing his 
own stories and scripts, 
designing the sets, help- 
ing to build them, select- 
ing his own casts, acting 
as wardrobe man, direct- 
ing the picture, and phot- 
graphing them as well. 

Then when the shad- 
dows of evening fell 
Mohr would retire to his 
improvised laboratory 
where he developed his 
negative and made his 
own first prints. Out- 
side of that he had the re- 
mainder of the day to 
himself. 

This was in San Fran- 
cisco. In that city he 
first started in a labora- 
torv at the salary of six 
dollars a week. Then 
he built himself a motion 
picture camera and started 
in the newsreel game. 

Then he shot a picture 
for Sid Grauman called 
“The Last Night on the 
Barbary Coast.” 

But Mohr was ambi- 
tious and joined forces 
with some people in 
Frisco who wanted to 
make three feature pic- 
tures, even though they 
had only $10,000 with 
which to do it. Mohr 


helped build the studio: then made the three pictures in 14 
weeks, went to New York and actually sold them all on the 
$10,000 budget, 

“It was a tough battle,” he explains, “but was a great ex- 
perience.” His was a one-man picture company from start to 
finish. And his pictures sold. 

This experience was followed by Mohr becoming a film 
cutter at $25 a week. But he was acquiring more and more 
experience and finally directed two single-reelers for Harold 
Lloyd. Then the war came on and he joined the army. 

At the close of the war Mohr came back to pictures and 
went to Portland, Oregon, where he was photographer, director 
and head cutter for a picture concern. Shortly after that he 
came to Hollywood and joined the ranks of “Poverty Row,” 
where for two years he was a Cinematographer. 

Eventually he landed as Mary Pickford's cameraman where 
he remained for a year and a half. Then he photographed “The 
Wedding March” and went to Warner Brothers where he shot 
“In Old San Francisco.” “Glorious Betsy,” “Heart of Mary- 
land.” “Noah’s Ark” and many other big pictures. 

Leaving there for Uni- 
versal he gave them the 
spectacle, “Broadway.” 
He followed this with 
“The King of Jazz,” the 
great Paul Whiteman pic- 
ture. He is under con- 
tract with Universal. 

At the present time Mr. 
Mohr has been loaned by 
Universal to Warner 
Brothers where he is 
photographing A1 Jolson 
in “Big Boy.” Several 
other studios have been 
trying to borrow Mr. 
Mohr to start with them 
at the finish of the War- 
ner picture, but Universal 
plans call for his return to 
that lot shortly. 

President Mohr has an 
ambitious program in 
formulation for the com- 
ing year’s A. S. C. activi- 
ties. A complete outline 
of this program will be 
published in this maga- 
zine next month. Mohr, 
a real progressive, plans 
some revolutionary moves 
in connection with the 
society along educational, 
technical and social lines, 
and the members of the 
American Society of Cine- 
matographers are looking 
forward to the ye(br with 
much assurance of its be- 
ing one of the most suc- 
cessful in the history of 
the organization which 
for years has exerted a 
world-wide influence.

^CHNIC OF 5^C0RDING CONTROL FOR 

Sound "Pictures 

« 

A Practical Discussion of An Important Subject 

By J. P. MaxHeld 

This paper is reprinted from the Technical Digest of the Academy of Motion Picture Arfs 
and Sciences. Mr. Maxfield is Supervisory Recording Engineer, Electrical Research Products, 

Incorporated. — The Editor. 


T he purpose of acoustic control in recording is to make the 
sound record so correlate with the picture, that the whole 
performance becomes pleasing to listen to and easy to un- 
derstand. It has been found that this result is obtained when the 
recording is so conducted that the voice, coming from the horn, 
appears to follow the speaker wherever he or she may go in the 
set, i. e. when an illusion of reality is obtained. 

Before considering this matter in detail, there are one or two 
preliminary points to be taken up. The first has to do with the 
nature of the material to be covered by this paper, which is dis- 
tinctly of a practical nature rather than a theoretical. Any theory 
which may be discussed is in the form of an explanation of why 
the technic operates as it does, the technic itself having been suc- 
cessfully used throughout several commercial productions. 

The second preliminary matter is a brief review of some of 
the material, which has been mentioned previously from a theo- 
retical standpoint, and which should now be discussed from the 
point of view of its practical use in the making of talking pic- 
tures. 

Dr. Knudsen discussed the curves shown in Fig. 1 . The dis- 
cussion here will deal only with the one marked E (n) . The 
vertical ordinate represents energy of speech, corresponding to the 
frequencies shown by the abscissa. Fortunately for those who 
have to operate the recording equipment, the high maximum oc- 
curring at approximately 200 cycles does not indicate maxi- 
mum intensity or the maximum amplitude, which is obtained 
at that frequency. The data represented by the curve was ob- 
tained in such a way, that the energy shown includes not only 
the amplitude or the intensity which occurs at any given fre- 
quency, but also includes how often energy of that frequency 
occurs in speech and also how long it is sustained when it does 
occur. The high maximum is brought about mainly by the fun- 
damental tones of the voice. Since the fundamental occurs in all 
of the vowel sounds, and since 
the vowel sounds are gener- 
ally held longer than the other 
speech sounds, it is seen that 
a large contribution to this 
high maximum is brought 
about by the time factor rath- 
er than the intensity factor. 

Dr. Knudsen also discussed 
the curve shown in Fig. 2, in 
which the ordinate shown at 
the right hand of the curve, 
represents sensation units ex- 
pressed in decibels, while the 
abscissas represent frequency or 
pitch. The lower line of the 
curve represents the threshold 
of audibility, while the upper 
line represents the intensity at 
which the sound becomes phys- 
ically painful. The useful 
range between these two turves 
is of the order of 100 to 120 
sensation units. It would 
appear at first sight, that the 
recording system, which cov- 
ers a range of approximately 
40 sensation units, would be 


totally inadequate. However, there are some features which 
limit the practical use of this whole range, other than those that 
reside in the recording system : First, the average noise in a 
theatre from the ventilators, audience, etc., is seldom less than 
30 sensation units above minimum audibility, and is frequently 
as much as 40. It is, therefore, useless to reproduce in the theatre 
any sounds less than 40 sensation units above minimum 
audibility, as they would become lost in this noise. Second, 
the upper 30 or more sensation units represent sound intensities 
of the magnitude encountered from the firing of big guns, large 
explosions and other uncomfortable loud sounds. 

Therefore, except for the few isolated cases, where records 
are being made of such explosions, the practical useful ranging 
has been reduced by 70 sensation units, and there remains only 
30 to 50 to be accommodated ordinarily. The Western Electric 
recording system can easily accommodate 30, and when properly 
maintained and operated, can accommodate 40. When it is con- 
sidered that the difference in loudness, between a stage whisper 
and a very loud shout is about 30 sensation units, it will be 
seen that the limits of the system do not ordinarily handicap 
recording. 

In the terms of the movies, Fig. 3 is a close-up of the curve 
shown in Fig. 2, with four additional curves added. These four 
curves represent the lines of constant loudness of 20, 40, 60 and 
80 loudness units above minimum audibility. The top and bot- 
tom lines are identical with the top and bottom lines respect- 
ively, of curves in Fig. 2. This curve indicates that in going 
from loudness 20 to 40, it is necessary to increase the grain of 
the amplifying system 20 db for the frequencies lying in the 
middle region. On the other hand, in order to go from a 
loudness 20 to loudness 40, at the low frequencies, say 
around 60, it is only necessary to go 6 to 8 db. However, 
loudness is mainly interpreted by the middle region. If, there- 
fore, a sound which was origi- 
nally made at loudness 20 
were reproduced by increasing 
the intensity by all its com- 
ponents by 20 db, it is ob- 
vious that the loudness in the 
bass would lie slightly above 
the curve representing a loud- 
ness of 60, i. e. more than 20 
loudness units too high. Such 
reproduction would sound 
over-bassed or “heavy.” This 
is one of the reasons why the 
human voice sounds heavy 
when reproduced at a level 
considerably higher than that 
at which the person actually 
spoke. 

This effect is inherent in 
the ear, and as the recording 
becomes more and more per- 
fect, the loudness level, or 
which music or speech is re- 
produced, becomes more and 
more important. This ends 
the preliminary review. 

The technic of acoustic con- 
trol is based on letting the

camera be the eye 
and the microphone 
be the ear of an ima- 
ginary person view- 
ing the scene. It 
mighe be interesting, 
therefore, to consider 
briefly how a person 
observes, that is 
how he sees and 
hears what is taking 
place around him. 

When a person is 
viewing a real scene 
in real life, he is 
viewing it , with 
lenses — that is. the 
eyes, and pickup de- 
vices — that is, the 
ears, which are in a 
fixed relationship, 
one to the other. 

This observer is 
equipped with two 
eyes and two ears. The two eyes enable him to appreciate 
distance or depth with much more facility than would be 
possible with one eye, while the two ears enable him to ap- 
preciate direction and perhaps, to a slight extent, depth where 
sound is concerned. The point of importance, however, is the 
fact that the eyes and ears maintain a fixed relationship to one 
another. 

The method by which direction is determined with either 
one or two eyes is obvious and need not be discussed. The 
factors which enter into the appreciation of depths or perspec- 
tive of sound are the ones of interest here. 

It is probable that the most important factor, particularly 
where monaural hearing is concerned, is that which deals with 
the relative change in loudness of the direct and reflected sound. 
Since the intensity of the reflected sound varies relatively little 
from place to place in a room, while the direct sound from the 
sources to the pickup device varies quite rapidly with its distance, 
the ratio of the intensity of the direct to the reflected sound also 
varies considerably. Hence, as a source of sound, such as a 
person speaking, recedes from the microphone the loudness of 
the voice appears to decrease slightly while the reverberation 
appears to increase materially. With binaural listening, this is 
unconsciously interpreted as distance. It has been found that 
this effect, when properly controlled, is also interpreted as dis- 
tance with monaural listening. 

In the case of the talking pictures, the camera has only 
one eye, or lens, and the recording system has only one ear or 
pickup device. Consequently those effects, which were brought 
about by the binocular seeing and by binaural hearing, cannot 
be made use of. Long experience with the photography has en- 
abled the camerman to create a part of the depth illusion by the 
proper choice of the focal length of the lens used, and by the 
proper type of lighting. Fortunately, for the acoustic engineer, 
the impression of depth depends upon factors which are almost 
as effective with binaural listening; namely, the change in the 
ratio of the direct sound to the reverberation present. 

The loss of direction, brought about by the use of one ear 
only, causes some rather unexpected results. When two ears 


CONTOtm UMS or equal loudness fon pure tones 



are used, a person 
has the ability to 
consciously pay at- 
tention to sounds 
coming from a given 
direction, to the par- 
tial exclusion of 
sounds coming from 
other directions. 
With the loss of 
sense of direction, 
which accompanies 
the use of the mon- 
aural hearing, this 
conscious discrimina- 
tion becomes much 
more difficult, and 
the incidental noises 
occurring in the 
scene, as well as any 
reverberation which 
may be present, are 
apparently increased 
to such an extent 
that they unduly intrude themselves on the hearer’s notice. It 
is, therefore, necessary to hold the reverberation, including 
these noises down to a lower loudness than normal, if a scene 
recorded monaurally is to satisfactorily create the illusion of 
reality, when listened to binaurally. 

This apparent increase in reverberation and incidental noises 
may easily be heard, by completely stopping up one ear and 
listening with the other only. It is easier to detect the effect 
in a room, where the incidental noises are fairly loud, and where 
the amount of damping is slightly less than in the normal liv- 
ing room. 

Since it is possible to create the illusion of depth or distance 
in both the visual and audible parts of the talking picture, it 
is necessary that the amount by which the voice appears to move 
forward and backward in the set, should correspond with the 
amount the image appears to move. The amount by which the 
voice appears to move forward and backward in the set, depends 
upon the amount of reverberation present, and upon the rela- 
tive distance of the microphone from the foreground and back- 
ground action. In general, the more reverberation present, or 
the further the microphone from the source of sound, the 
greater is the apparent distance of the voice from the near fore- 
ground. It has also been found by experience, that if the con- 
ditions have been made correct to obtain this illusion, then the 
voice or sound also appears to follow the picture across the 
screen. 

There is one important difference between the imaginary ob- 
server in the scene and the taking of a talking picture. The 
real observer maintains his pickup device, namely ears, at the 
same distance from the scene as his lenses, that is eyes. This 
is not necessarily the case with the talking pictures, as the 
cameraman may at will, use lenses of different focal lengths, 
whereas the observer cannot change the focal length of his eyes 
beyond that amount required to accommodate focus. The use 
of long focus lenses by the cameraman is equivalent to a means 
of bringing distant action into the near foreground. When such 
action is brought into the near foreground by the use of the 
closeup. it is also necessary to pull the sound up, so that it ap-

Unscheduled Drama in a Monitor Room 
By 'William Stull 


T he man at the desk looked up. “ ’Morning, Smith. Guess 
you’re in for another holiday today. Steinberg’s still pick- 
ing his cast.” The telephone buzzed stridently. ‘‘Sound 
department — Johnston speaking .... Oh yes, Mr. Steinberg 
.... Where? .... All right. I’ll send you a crew right away.” 
The instrument rattled back into place. 

‘ Well, Smith, you’re in luck after all. Someone’s brought 
the Dutchman a new blonde to play his lead, and he wants a 
test of her right away. Going to shoot it on Stage 6 — you 
know the Brandon company’s working the night shift there, 
and their set-up hasn’t been struck yet. No time to check the 
channel, but it’ll be okay for a test. You’d better hurry right 
over, so they’ll know we’re on the job. I’ll send the boys 
along after you.” 

As the door swung shut, Johnston turned to the man sitting 
opposite him. ‘‘Sorry, but when Steinberg calls, everyone on the 
lot has to jump. Just a moment more.” 

He leaned forward and spoke a few crisp orders through a 
dictaphone on his desk. 

Then, picking up his cigar, ‘‘You sure were right when 
you said this is one queer game. Some of the things I’ve run 
into since I’ve been out here . . . . ! Well, you saw that fellow 
who just looked in here? His story’s about the strangest I’ve 
hit yet. On the payroll here his name is John Smith — but 
when he was my boss back East in the telephone Lab. he had 
another name, and could tack half the alphabet after it, if he 
wanted to; he was one of the real big shots in the engineering 
way. Had a big division of the lab. under him, and practically 
a free hand in running it. They said he drew down almost as 
much money as some of these stars out here are supposed to: at 
any rate, he had nothing to worry about — had a fine home, a 
firie job, and a wife — and what a wife! Pretty? More than 
that — a real beauty 1 I saw her once or twice when she came into 
the lab. to see him. Tiny little thing called Doris, she was, with 
a mass of fluffy, golden hair, big, blue eyes, and a figure that 
would give Zeigfeld a thrill! Of course he was crazy about her, 
and she about him. You could see that. 

‘‘Then one morning the chief came in drunk — dead drunk. 
Not cockeyed, but sodden, blind drunk: at least he acted that 
way. Plodded into his office like a machine, and plodded out 
a few minutes later just as though none of us were there. 
His secretary found a note of resignation on his desk when 
she went in and the chief never came back. 

‘‘Yes, he just vanished. No one seemed to know a thing 
about him, or where he’d gone to. Guess the police figured 
he’d jumped into the river, and gave it up; it was midwinter, 
and of course there was no hope of finding his body, if he 
had. Anyway, that big Walford affair came off the next day, 
and attracted everyone’s attention. 

‘‘For my part, after the excitement in the office died down, 

I was too busy to think any more about it. They keep you 
busy in those big research plants! In due time, the wife col- 
lected the estate, and a nice fat parcel of insurance, and I didn’t 
hear much more about her, except now and then I’d see a bit 
in the paper about her work in the ‘Little Theatre’ movement, 
or about her having been to some affair with Hubert Allston, 
who was some sort of a writer with her particular group. 

‘‘In time, I got my promotions, and when the talkie rush 
came, I was one of the first men they sent out here. A couple 
of months after I’d gotten out here, I had to go on location 
with one of the units down San Pedro way. During the day, 
who should I spot in the crowd watching us but my old chief 
— down and out; a regular bum! Lord! I never saw a hobo 
look so hungrily at a steak as he did at the sound apparatus we 
had ! Poor devil, he’d designed most of it, and fought for it 
when almost everyone else in the outfit thought it was just a 
crazy notion. No wonder he gaped at us like a Stella Dallas in 
pants. Next to his wife, his work had always been the biggest 
thing in his life. 


‘‘As soon as I could get away, I got to him, and tried to 
make him come in with me and see some of the big guns on 
the lot, but he wouldn’t. Talked a lot about being better off 
as he was, and all that, but I could see he was longing for the 
old work again. Well, finally I got him to come on as a mixer, 
under this Smith alias. Good mixers were scarce then, and there 
was no question of landing him a berth. Since then he’s spruced 
up a lot, and developed into the best mixer on the lot — but 
he still seems sort of dazed in his mind, a good deal like my 
brother-in-law is, who was shell-shocked in the war. When it 
comes to his work, though, he’s the real McCoy, all right — 
and, y’know, I think he’s really happy up there in that stuffy 
little booth of his ” 

* * * 

TT^HEN “Smith” reached Stage 6, he found that others had 
preceded him, and the deserted set was again assuming a 
semblance of life. A number of overall-clad electricians were 
checking the lights and wiring, under the watchful eye of Pete, 
the head “gaffer,” while a small army of ‘grips’ were trundling 
another big camera booth into place beside the one in which an 
energetic assistant-cameraman was already setting up a camera 
for Dick Miller, Steinberg’s inevitable photographer. Miller 
himself bustled over to where the head gaffer stood beside the 
single ‘rifle’ light that illuminated the set, and outlined the 
changes he wanted made in the lighting. 

“Smith’s” eyes travelled rapidly over the sound equipment. 
Yes, everything was about right as it stood. Might have to 
lower that mike on the new boom a trifle — probably not, 
though, unless she was extra short; it was one of the good 
ones. That other cable — where did that lead? Oh yes! This 
was Herb’s set: must be that gag Herb was so fond of — 
hiding a special mike in some fake books on the table. Impos- 
sible notion. Sound reflected among all that junk on the table, 
and lost half the high frequencies before it even hit the mike — 
and the condenser had to be so far away that it got worse 
before it ever reached the amplifying panels. Silly fool notion. 
Herb’s. It would never do anyone any good; you couldn’t 
make a decent recording with the thing, no matter how long 
you tried. Never, not in a million years. Funny, there must be 
another mike hooked up somewhere, too. His eyes followed the 
slim, rubber-cased cable away from the junction-box at his 
feet. H’m. Off to one side, over a little set adjoining. Of course! 
He’d forgotten. Brandon had been working here last night. 
Brandon always made his pictures that way — set up a flock of 
cameras, hooked in all the mikes he could get, and tried to shoot 
a whole sequence at a time. Silly fool. No wonder his pictures 
were lousy. Damn these boy wonders who tried to break pro- 
duction records 

He turned to Dick. “How many cameras are you using for 
this test?” he inquired. 

“Three,” came the cameraman’s brisk reply. “Two long- 
shot cameras in the big booth — one of them is for color — and 
my own in the little one. making close-ups with a four inch.” 

“All right with me. You’ve good motors and plenty of 
cable? Then I’ll go on upstairs. Tell the microphone man to 
give me a buzz when he gets here.” He turned on his heel and 
started toward the stair that led to the monitor room. 

As he reached the door, he found himself confronted by the 
swart German director. Steinberg, removed his inevitable, lean, 
brown cigar from his mobile mouth, and smiled. “So,” he 
beamed. “That is good. I am glad you hof been here assigned. 
Ve must the best recording of this test hof — I s'ink I haf my 
leading lady at last found .... Mein Cott! Sie so wiinderschone 
istl If only she records well now! But you will fix that,

5*. C ^^ember First ^JMan to 
"Photograph Famous Shadow Pands 

Charles G. Clarke Wins Praise of Scientific World 
for Accomplishing Feat First Time in History 


F or the first time in the history of the science of Astron- 
omy scientists succeeded on April 28th in photograph- 
ing the elusive “shadow bands’’ that accompany an 
eclipse of the sun. 

And this feat, which has stirred scientific circles throughout 
the world was performed by Charles G. Clarke, a Vice-Presi- 
dent of the American Society of Cinematographers, and prom- 
inent Hollywood Cinematographer employed at the Fox studios. 

Clarke’s extraordinary cinematographic feat was accomplished 
while he was at the Mt. Wilson Observatory Eclipse Camp, 
located near Honey Lake, California, under the auspices of the 
American Society of Cinematographers, which threw its re- 
sources at the disposal of the astronomers in their efforts. 

Clarke photographed the shadow bands for a period of five 
minutes during the central phase of the eclipse of the sun, using 
specially prepared glass screen fastened on two 20 -foot poles 
and held between the camera and the sun. 

According to the Mt. Wilson astronomers, Clarke’s pictures 
show the definite direction and curvature of the bands which 
the scientists say will definitely help to determine whether they 
originate on the surface of the moon or from the earth. This 


is a problem that has never been solved, although scientists have 
been working on it for years. Still cameras could never catch 
the shadow bands, but the motion picture camera did. 

Daniel B. Clark, former president of the A. S. C., became 
interested in the eclipse shadow bands problem when he heard 
scientists discussing it, and immediately he took the matter up 
with the Board of Governors of the American Society of Cine- 
matographers. He outlined the problem to the members of the 
board and pointed out the feasibility of mastering this puzzle. 
The A. S. C. Board of Governors immediately placed its re- 
sources behind the project and gave the word to go ahead. 
Dan Clark at once picked Charles G. Clarke as the logical man 
to make the attempt. He has photographed eclipses both here 
and in the Northwest and has a record as a daring aerial adven- 
turer in the Alaskan wilds. 

The preliminary tests were conducted at the physical lab- 
oratory of Mt. Wilson Observatory. 

Dr. John A. Anderson, physicist, created an artificial sun 
eclipse, and Dr. Seth B. Nicholson, astronomer, checked its sim- 
ilarity to a true eclipse.

Success! 

P erhaps this wall may seem out of place in a magazine 
devoted to technical matters, but it is on the editorial chest 
and must come off. 

This writer has often wondered why men when they attain 
a certain measure of so-called worldly success suddenly forget 
friends of the past; often friends who have helped them in 
days when the world was mighty drab and the pay check was 
merely something hoped for. Nowhere do you find men of 
this type in such profusion as in the motion picture industry. 
Why? That is a problem that has often been discussed. And 
it is not among the actors that this spirit is found. They, bless 
their hearts, are too lenient with their friends for their own 
good. 

It is among the executives, directors and writers that suc- 
cess seems to swell the head, blot out the memory and har- 
den the heart. The other day a man dropped into this office 
and told of a “former” friend of his, now a big studio executive. 
This man only a few years ago was plugging along in New 
York on starvation wages. Our friend gave him a helping 
hand and as a result started him directly on the path that led 
to his present position with a salary of four figures weekly. 

But, our friend couldn’t get him on the telephone, although 
he tried for a week. Only a chilly-voiced secretary would talk 
and say her employer was “in conference.” So our friend went 
to the studio and there was told by an office boy that the ex- 
ecutive was too busy to see him and expected to be for a 
month. 

Typical of what success in the picture business does to so 
many! What a shame! After all, we wonder if they have at- 
tained success. 


Again, A. S. C-! 

C 'ONGRATULATIONS are in order for Clyde De Vinna, 
■* one of the best known members of the American Society 
of Cinematographers. He has just been awarded the highest 
honor the motion picture industry can give for outstanding 
cinematography. Mr. De Vinna was given the award of merit 
of the Academy of Motion Picture Arts and Sciences for “his 
distinctive achievements in photographing the unique motion 
picture. ‘White Shadows in the South Seas’.” In other words, 
the honor of the most outstanding piece of cinematography 
for the period between August 1, 1928 and August 1, 1929. 

Last year the award went to Charles Rosher and Karl Struss, 
both members of the American Society of Cinematographers. 


Color 

E ARE wondering what will happen during the com- 
ing year in the development and use of color in the picture 
industry. For a time it seemed as though color would com- 
pletely, or nearly, wipe out black and white photography. 

Now, however, there seems to be a gradual change back 
to black and white. This is partly due to _ inability to get 
sufficient release prints in a short time. Will this stop the ad- 
vance of color? After all, the prize of the Academy of Mo- 
tion Picture Arts and Sciences for outstanding photography 
went to a picture in black and white. Time will tell. 


O, Dear! 

Even out here in California, where we have perpetual sun- 
shine and glorious weather all the year, one begins to feel the 
breath of Spring creeping in at the well-known window these 
days. After all. it must be the time of year, rather than the 
weather that gives one that tired feeling, which can be tossed 
aside only by the prospect of a fishing trip. Takes one back 
to those old days long ago on a Pennsylvania farm where we 
used to cut a birch pole, use ordinary string for a line, and — 
B’Gosh, catch the finest speckled beauties in the world! 


Those Hog Callers! 

W E HAVE felt all along that someone would make us 
sorry that we have developed talkies. Now we know that 
our hunch was right; for from Washington comes the word — 
and from no less an authority than our good friend. Raymond 
Evans, Chief of the Office of Motion Pictures of the Depart- 
ment of Agriculture — that hog calling is soon to be recorded. 

Pity the poor pigs on the farms when home talkie apparatus 
is installed and just as the porkers settle nicely in a deep mud 
puddle a persuasive “whooee” will come floating through the 
air in full bucolic strength, or what have you I 

And, we bet a plugged nickel against a stale doughnut that 
after the hog calling is recorded we will hear those “husband 
calling” contests on the films. Probably there will be a lot 
of husbands rushing from the darkened theatres of the land 
when the resonant v'oice of a hubby-calling wife booms out 
from a news reel. 


Cinematographic Annual 

A t last, the Cinematographic Annual is on the press. 

And, perhaps it is best to say a few words at this time 
in the way of apology for being a month late in our sched- 
ule. We had hoped and expected to have the book off the 
press sometime in April. But when we found that we would 
have to leave out certain articles that we believe will be of 
tremendous interest and value, the board of editors thought it 
best to be a little late. So, you who have been waiting for it 
have our apology. We trust that the quality of the book will 
more than make up for a month’s delay. 

Speaking for the entire board of editors, this w'riter takes 
the opportunity to say a few words regarding this book, which 
we really believe will be the most outstanding publication yet 
to appear in connection with motion picture making, either 
professional or amateur, and what we say we have no fear 
will be contradicted when you readers see it. 

We have tried to make this a book that will not only be 
interesting, but will be instructive as well. This, in itself, has 
been quite a task; in fact, a tremendous task. However, we 
have received the cooperation and assistance of many of the 
biggest figures in the technical world, and to them will be for- 
ever grateful. 

As regards things purely cinematic, we turned to the men 
who are photographing pictures, and they have given us some 
articles that we feel will be of great help to the readers of the 
book. All the years of their experience have gone into their 
articles, and naturally, they are the last word in authenticity. 

For sound we received the magnificent aid and cooperation 
of the biggest sound engineers and of the Academy of Motion 
Picture Arts and Sciences. The Academy, with the cooperation 
of the leading sound authorities of the industry conducted an 
excellent technical course in sound during the past winter. A large 
part of this course will be found in the Cinematographic Annual, 
through the courtesy of the officials of the Academy. 

The biggest scientists of the industry cooperated in the prep- 
aration of the laboratory and theoretical articles. All in all. 
we believe you will find in this book just the type of publica- 
tion you have been looking for. 

And the amateurs, or home movie makers, will find it a ver- 
itable gold mine of information. A special section has been de- 
voted to their needs. A special elementary course in cinemato- 
graphy will be found here which should make their tasks much 
lighter, and their 16 mm. pictures much more satisfactory. We 
feel that no amateur should be without this volume. 

In the statistical department will be found tables and form- 
ulas that will be invaluable. 

As we stated at the beginning, there will in all probability 
be things omitted which we would like to see, but by and large, 
we feel that we have a book that every person in any way 
connected with the industry, either in sound cinematography, 
theatre, laboratory, or the home movie maker will find of un- 
told worth to them. — H. H.

Technic of Recording Control 

(Continued from Page 12) 

pears to be coming from a similar distance, that is from the 
image on the screen. 

There is one other point to be kept in mind regarding the 
analogy between the imaginary observer and the talking picture 
equipment. If a speaker in the scene walks away from the 
imaginary observer, he walks away from both his eyes and his 
ears. It is, therefore, necessary to place the microphone in the 
same approximate direction from the action as the camera, in 
order that the speaker shall approach the microphone when ap- 
proaching the camera and vice versa. 

In view of the above, it cannot be too strongly stressed that 
it is important to use one microphone only for a given camera 
position. Naturally if the camera position changes during the 
scene, the microphone position should change accordingly, so 
that the proper relation between the ear and eye is maintained. 
The insistance on this requirement on one of the early pictures 
made, led some humorist to call this technic “The Trail of the 
Lonesome Mike.” It should be noted from previous paragraphs; 
one microphone position only for one camera position. There 
are some cases involving complicated setups, where closeups and 
long shots are being attempted simultaneously, where more than 
one microphone may be legitimately in the set at one time, but 
only one of them should be on at any given time. The one that 
is on, naturally should correspond with the camera whose pic- 
ture is to be used in the final cut. This use of closeup and long 
shot simultaneously, requires a knowledge of how the scene 
is going to be cut, and should, therefore, be avoided if there 
is any doubt about cutting. 

During one *of the first pictures that was made with this 
technic, the studio people were coaxed into making the sets with 
sufficient reverberation to produce the depth effect. The set in 
question was about 25 or 30 feet wide and some 35 feet long 
and approximately 24 feet high, as shown in Fig. 4. It repre- 
sented a large hall in an old fashioned European home, and there 
was an entrance onto a stairway from a second story room at 
the back of the set. The dialogue was started in the middle fore- 
ground by a man at A, and then a young lady came out of the 
second story room at B, and said a few lines, the dialogue con- 
tinuing until both people were at the foot of the stairs at F. 
midway back in the set. The studio people insisted on making 
a closeup and a long shot simultaneously, and as the long shot 
covered a considerable angle, it was impossible to get a micro- 
phone into the scene sufficiently near the young lady to take 
care of a sound track for her closeup at entrance. When the 
rushes were shown in the review room, the first to come thru 
was the long shot, and the result was exceedingly good, the voice 
appearing to come from the mouths of the speakers. The sec- 
ond rush showed the long shot scene with the closeup of the 
young lady cut in at the proper place. This picture, however, 
was coupled up with the only sound track available, namely, 
the long shot sound track. Of the five people in the review 
room, three unconsciously moved their heads to one side to 
see around the girl, in order to find out who was speaking in 
the room behind her. The effect was so disconcerting that it 
was necessary to retake the closeup with its own sound track. 

Since the interpretation of distance by the microphone de- 
pends upon the acoustic properties of the set, there is only one 
microphone distance at which the proper sound distance will be

obtained. This is analogous to limiting the cameraman to a 
single lens for his camera. Hence, when a change is made to a 
long focus lens, it is necessary to move the microphone nearer 
the scene than was necessary for the shorter focal length. 

It is now time to consider how much the microphone must 
be moved when the lens is changed. With sets built in the man- 
ner to be described later, the microphone should be as far away 
from the foreground action as it would be necessary to place a 
30 to 35 millimeter, in order to obtain the same sized image 
as will be obtained with the long focus closeup lens actually 
in use. 

Fortunately, if the difference in focal length between two 
cameras used simultaneously is not too great, the ears’ interpre- 
tation of the depth effect is not sufficiently accurate to cause 
any trouble. It is, therefore, possible to use a 35 to 40 milli- 
meter lens simultaneously with a two inch lens without diffi- 
culty, provided the depth of action is not over 12 to 15 feet. In 
scenes of ordinary living rooms, no trouble would be caused by 
this arrangement, provided the two inch lens is not brought 
much closer to the subject than the shorter focus one. 

Figure 5 shows two views of the same set and the same 
action, the right hand section indicating the situation for a long 
shot, while the left hand section indicates the camera and micro- 
phone positions for close-ups of each of the three dialogues, 
namely, those at positions 1 , 2 and 3 respectively. The long 
.shot was made with a 35 millimeter lens, whereas the close-up 
cameras were equipped as follows: Camera for position 1, 4", 
for position 2, 6" and for position 3, 4". The corresponding 
microphones are shown. It will be noted in the close-up section 
that three microphones were in use, but it should be further 
noted that only one was used at any one time. That, is when the 
dialogue was taking place in position 1, its microphone was on, 
and similarly for positions 2 and 3. The action occurring during 
the transition from positions 1 to 2 and 2 to 3, was taken care 
of by the long shot made under the conditions shown in the right 
hand section. 

The next major item deals with the designs of the set, with 
a view to obtaining the proper conditions for the acoustic per- 
spective. When a person listens with two ears in a real scene, 
he is able by his sense of direction, to pay attention to the sound 
coming directly from the speaker, to the partial exclusion of 
the reflected sound and incidental noises coming from all around 
him. However, with this sense of direction destroyed by the use 
of one ear only, he is no longer able to make this discrimination, 
and the reflected sounds, that is, the reverberation and incidental 
noises, appear to increase in intensity. It is necessary, therefore, 
to insure that the sets have less reverberation than would have 
been actually present in the real scene. It has been found by 
experience, that if the walls of a three walled set are built of 
materials having similar acoustic properties to those depicted in 
the real scene, that the absence of the ceiling and end wall pro- 
vide sufficient damping to render the acoustics suitable for re- 
cording. This of course assumes that the sound stage is dead, 
or that the set is built out of doors. In practice, however, it 
would be both inconvenient and expensive to build the walls of 
a set of the materials that would really have been used had the 
scene been a real one. It is necessary, therefore, to use imita- 
tions. These substitutes should imitate acoustically the real

CONTiNUOUS PRINTER 


I N ORDER to fulfill the technical and commercial exigencies 
imposed upon the motion picture laboratories by the advent 
of sound pictures, it was found necessary to devise means by 
which the accurate and rapid printing of the sound negative 
could be conducted independently from that of the picture record. 

The well known characteristics of sound recording and re- 
producing demand an extremely smooth and continuous mo- 
tion of the film in front of the scanning slit, as well as a perfect 
control of the sources of light which impress the film upon 
which the sound record is registered or excite the photoelectric 
cell in the process of reproduction. The meticulous care with 
which a film sound record is made would be of no avail if 
the printing process of the sound negative could not be con- 
trolled with equal certainty and accuracy. 

From the early in- 
ception of sound pic- ■ 

tures, it was evident 
that the Bell 
Howell Continuous 
Printer answered all 
the requisites of 
sound pictures, be- 
cause through years 
of patient research it 
had reached such 
point of develop- 
ment that all the re- 
finements ^ost ap- 
propriate to take 
care of absolute film 
registration were in- 
corporated in it. It 
remained to devise 
means by which the 
printer could rapid- 
ly and with least in- 
convenience to both 
laboratories and pro- 
ducers be made 
adaptable to the new 
conditions. 

The Bell ^ Howell 
engineers happily 
solved the problem 
by designing a Triple 
adjustment sound 
printing attachment 
which can be adapt- 
ed to all Bell W 
Howell printing ma- 
chines in existence, 
and, of course, to all 
apparatus being 
manufactured. 

In order to fully 
appreciate the prob- 
lems involved and 
the unique manner 
in which they were 
solved, let us sum- 
marize the require- 
ments imposed. 

(1). It was de- 
sirable that existing 
equipment could be 
used.

attachment should 
preferably require on- 
ly nominal altera- 
tion and fitting.

light control for printing the sound and picture portions inde- 
pendently should be insured. 

(4) . If possible, the attachment should permit printing 
either the sound or the picture area from either end of the roll, 
to eliminate waste time in rewinding. 

(5) . It was desirable that it comply with the standards ap- 
proved by the Society of Motion Picture Engineers, whereby a 
black light shield is to be printed along the sound track to 
eliminate any possibility of variation of tone in sound repro- 
duction due to a possible side motion of the film in front of the 
scanning slit of the projection apparatus. 

(6) . The device should be convenient, quickly set at any 
desired adjustment, positive and accurate. 

(7) . It was desirable to have the masks arranged so that 

the full negative

could be printed at 
one adjustment. 

The following de- 
scription will ex- 
plain clearly how 
very effectively the 
Bell Howell Com- 
pany have solved this 
problem, and the 
figure illustrating this 
article will clearly il- 
lustrate the workings 
of the attachment. 

At 1 and 2 the 
triple adjustment 
sound attachment is 
shown installed in 
the standard Bell 
Howell Continuous 
Printer. The attach- 
ment itself consists of 
two main assemblies 
— the masking unit 
and the operating 
lever unit. 

The masking unit 
is installed in place 
of the usual top 
aperture plate. After 
it has been accurately 
adjusted in the print- 
er, a hole is drilled 
through the top of 
the printer casting 
into the masking 
unit, and tapped. This 
insures the masking 
unit always being 
held in perfect align- 
ment. 

The operating 
lever unit is then in- 
serted through an ac- 
curately milled slot 
in the printer casting 
so that the levers en- 
gage the masks prop- 
er. The operating 
unit is then fastened 
permanently in posi- 
tion. 

At 2 is plainly 
shown the manner in 
which the sound at- 
tachment is arranged.

De Vinna Wins Academy Award 
For Outstanding Photography 



Clyde De Vinna and trophy awarded him for outstanding 

cinematography 

"y HE HIGHEST honor that can be paid an American Cinema- 
tographer has been bestowed upon Clyde De Vinna. A. S. 
C., for his work in photographing “White Shadows in the 
South Seas.” 

This honor consists of the award of merit of the Academy 
of Motion Picture Arts and Sciences. The award was based 
on feature pictures released in Los Angeles during the year 
ending July 31, 1929. The prize is a beautiful gold statuette, 
and was presented to Mr. De Vinna by William C. deMille. 
President of the Academy, at a banquet held at the Ambassador 
Hotel. 

Mr. De Vinna has been in the motion picture field for many 
years and has long been recognized as one of the outstanding 
cinematographers of the industry. Prom his camera has come 
many unusually beautiful pictures, but when “White Shadows 
in the South Seas” made its appearance De Vinna was shower- 
ed with praise from all parts of the world. The sheer beauty 
of the photography in this picture brought gasps from audi- 
ences all over the world, and when De Vinna landed in Lon- 
don a year ago, on his way to Africa, he was called to be 
the special honor guest at the London opening of the picture. 

Poliowing the completion of “White Shadows in the South 
Seas,” De Vinna returned to the “The Pagan,” another pic- 
ture which excited much comment for its cinematography. He 
then went to Africa as chief Cinematographer on “Tader 
Horn.” Reports from the MGM studios indicate that he has 
another pictorial delight in this one. 

Among the other awards of merit given by the academy 
are the following: 

To Warner Baxter, for his distinctive performance in “In 
Old Arizona;” Mary Pickford for her work in “Coquette;” 
to Frank Lloyd for his directorial work in “Weary River,” 
“The Divine Lady” and “Drag;” Cedric Gibbons for his art 
direction in “The Bridge of San Luis Rey:” to Hans Kraly 
for writing the story of the artistic motion picture. “The 
Patriot.” Metro-Goldwyn-Mayer Corporation was awarded first 
honors for the production of “The Broadway Melody.” 


Rumania 

T^OLLOWING general unemployment of musicians in Ru- 
mania, which is claimed to be caused by the advent of sound- 
film, the Minister of Labor has prohibited the activities of for- 
eign musicians in the country, with the exception of those who 
come to work in Rumania, as members of an orchestra, of en- 
tirely foreign origin. 


Putting Industry in the Movies 

(Continued from Page 9) 

spots: balloons, seaplanes, airplanes, the tender of a locomotive, 
on a speeding fire engine, on a monorail crane 75 feet in the 
air, on the world’s largest electric shovel, on top of the frame- 
work of a bridge 175 feet in the air. I could go on until the 
list became tiresome. 

The average two or three reel industrial production contains 
about eighty per cent of interiors and requires about seven work- 
ing days for shooting. The crew consists usually of a director, 
cameraman, electrician, two to five assistants, and a man from 
the factory. 

Often we find ourselves in difficult spots as regards light 
placement. Sometimes we have to take the lights all apart, carry 
the parts through peculiar places and put the lamps together 
when we get them where we want to set them up. I recall one 
job on which we had to do this and in order to do it had to 
have the plant shut down for just fifteen minutes. We had to 
make it fast for production cost was $1000 an hour in the 
plant. The great variety of subjects we are called upon to 
photograph makes our business an enjoyable, if at times a 
trying one. This week wc may be up in Glacier Park working 
on the edge of a treacherous ice crevice where a slip of the foot 
would mean almost certain death. Next week the same man 
may be shooting some humble home in connection with a 
“drive” for a Community Fund. Or perhaps, he may be photo- 
graphing a surgical operation in a hospital. 

One of the most unusual bits of work I have ever done in 
the line of industrial work was the making of a two-reel pro- 
duction in which snakes, lizards, alligators, scorpions, turtles 
and birds were the principal subjects. The climax of the picture 
was to be a scene showing “Huckleberry Finn,” a tame, four- 
foot rattlesnake, shedding his skin. But that was something we 
could not hurry. No one but the snake could do that and he 
wouldn’t do it until the psychological time. 

The snake’s owner watched him day after day, waiting for 
the peculiar look of the snake’s eyes which would just precede 
the start of the skin shedding operation. But that snake just 
wouldn’t shed! 

And then — at three o’clock one morning I was awakened by 
the ringing of the telephone. The excited snake owner was on 
the phone yelling that “Huckleberry” was about to shed. 

“Bring him over to the studio,” I answered. 

So, he dashed through the early morning darkness and in 
twenty minutes the snake was lying on the floor beneath my 
camera. And the way that snake wriggled was a sight one could 
never forget. When the old skin had been shed, believe it or 
not, that snake actually looked proud! 

I could go on indefinitely, but at this point thing it best to 
do a fadeout. 


Germany 

B erlin exhibitors are up in arms against the Berlin munici- 
pality, which has entered into direct competition with 
them. The municipality is starting a film department “for the 
production and exhibition of film records of events and work in 
the Metropolis.” The Berlin Eastern suburb of Lichtenberg has 
done this sort of work for a considerable time the Municipal 
Film Archive and Picture Theatre of Lichtenberg, located in a 
school house, completed its tenth year last week. Now that 
the Berlin Municipality is to follow this example, the Exhibi- 
tor’s Association is reported to take action. During the past 
year the Lichtenberg authorities showed 30 feature films certi- 
fied as “educationals” at prices with which no exhibitor can 
compete. These “educationals” included also entertainment fea- 
tures. The Berlin Municipality runs a Grand Opera House, 
concerts, lectures and other entertainments at a loss. 


Warner Engineers Make 37-Pound Camera Case 
A camera case weighing 3 7 pounds, as against the thousands 
of pounds of the present sound-proof camera booths, has been 
developed by Warner engineers. Called the “Warner Brothers 
Blimp,” the device, which is also proof against fire and water, 
is to be placed on the market, with Continental Accessories Co. 
as the distribiutors.

B. ^ H. Continuous Printer 

(Continued from Page 19) 

Note carefully how the masks of the sound attachment inter- 
lock with the lower aperture jaw to prevent light leakage. 

In the early models of the B. K H. Printer, the printing light 
was controlled through the mobility of the jaws of the printing 
aperture. By enlarging or reducing the printing aperture more 
or less exposure was given the positive film for a uniform 
running speed of the machine. 

A refinement developed a few years ago added a new method 
of light control called the “back shutter,” which, as its name 
implies, consists of a variable aperture shutter located at ap- 
proximately mid-distance between the printing light and the 
aperture. The versatility of this method of light control is so 
great that it permitted to dispense with the varying in width 
of the printing aperture itself while retaining a great range of 
light intensities easily controlled from the outside of the ap- 
paratus. 

The “back shutter” proved invaluable in the development 
of the triple adjustment sound attachment, because it permitted 
to stabilize the printing aperture to a standard 5-16" dimension 
which is also the height dimension of the triple mattes. 

The “back shutter” method of light control is applied to 
the independent printing of both the picture or the sound 
record, as the occasion arises. 

Now let us turn for a moment to a consideration of the 
actual manner in which the three masks are arranged so as to 
control the final result in the print. At Fig. 3 is shown the 
complete unit so that its action can be more clearly visualized. 

Three masks are employed, the width of the center one being 
— .750" and of the two side masks — .170" each. They are 
made so that they fill the 5-16" high opening. These masks 
are made to very close limits, as may be expected, to insure ac- 
curacy in their action, and eliminate the possibility of light 
leaks at their adjacent sides. 

Each mask operates in accurately milled control slots in the 
main casting. On the under side, each mask has two slots cut, 
into which the pawls P (Fig. 3) engage. These pawls are held 
in place by the triple-tongued Spring S (Fig. 3). The slots 
in the masks are Vi " apart, so that the stroke of the masks is 
Yi ". This withdraws the masks sufficiently far back to avoid 
any interference with the printing light. 

Figure 2 demonstrates this more clearly than any further ex- 
planation. 

The middle mask is cut away just back of the part that 
blocks the aperture. This recessed portion comes within 1-16" 
of the front and is arranged so as to avoid any possibility of 
fringing due to reflections from the sides of the masks. In prac- 
tice. it insures the line between the picture and sound areas 
having sharply defined edges. 

The two side mattes arc milled with a slight rib on the 
sides adjacent to the middle mask. This rib is % " from the 
front of the mask and protrudes .014" from its side. 

When the middle mask (B Fig. 3) is pulled back, it en- 
gages this rib on the side mask and moves it over sideways. The 
mask is moved .017" at the aperture itself. This means that 
sound track does not cover as much space adjacent the picture 
area as it did before. Therefore, that portion of the film now 
uncovered (.017" wide) receives a double exposure, which re- 
sults in a black line, or light shield between the picture area 
and the sound track. 

Reference to the dimensional drawing (Fig. 9) and to 
Figures 4, 5, 6, 7, and 8 will show exactly what goes on. 
When the middle mask B (Fig. 4) is drawn back it engages 
the mask A (Fig. 5) and pushes it to the left. In this position 
the mask A (Fig. 5) covers the sound track proper and the 
portion of the negative marked Y (Fig. 9) is printed. However, 
when the sound track is to be printed the mask A (Fig. 6) is 
set back and the area marked X (Fig. 9) is printed. This over- 
lapping of the two exposures produces the black line between 
the sound and the picture area. As stated previously, the over- 
lapping is adjusted so that this line has a width of .017". To 
insure clarity in presenting this explanation of the modus 
operand! of the masks, it was assumed that the film was re- 
wound between the printing of the sound and picture areas. 

Now let us assume that we have printed our picture area 
as before with the masks set as in Fig. 5. (The negative will be 
in the forward running position) . Then if we desire to print 
the sound area without rewinding, we remove both the positive 
and negative films from the take-up spindles and put them on 
the feed spindles. The printer is again threaded up and the 
masks set in the position shown in Fig. 8 instead of position 6. 

Reference to the captions given in the figure will show how 



the masks are set for different conditions — it is obvious that 
the versatility of this sound attachment is all that can be de- 
sired. It can also be accepted that its accuracy is likewise. 


Movie Congress at Algeria 

TOURING the festivities to be organized in spring, to com- 
memorate the hundredth anniversary of Algeria as a French 
colony, an international educational film congress was held there 
last month. The congress comprised an exhibition of the most 
current types of film projection apparatus, cameras, etc. ; lec- 
tures and films on public health and hygiene. The admission 
for exhibitors and the public, both to the exhibition hall and 
to the lectures, was free. The aim of the congress was to propa- 
gate the idea of motion pictures as a means of tuition. 


English Tax 

T T IS reported that theatres in Great Britain and Ireland con- 
tributed roughly 6,000,000 pounds last year to the Treasury 
in entertainments tax. The sum paid to the Treasury on this 
account from picture houses for the four months of last year, 
April to July inclusive, was 1,926,682 pounds, which was 
equivalent, roughly to 6,000,000 pounds a year. The fact 
that the picture public paid this vast sum was one more proof 
of the immense hold the cinema had on the British public, it 
was claimed.

Technic of Recording Control 

(Continued from Page 18) 

materials as nearly as possible, and in particular should be 
braced sufficiently so that they do not tend to materially partake 
of the vibrations set up in the air by the sound. 

When a set has been designed in this manner, experience 
has shown that the incidental noises sound more realistic and 
convincing, and that they may usually be recorded at the time 
the original scene is taken. In one picture, on which this technic 
was used, some dramatic scenes occurred which were to be in- 
tensified by a period of sudden silence. In order to accentuate 
the silence, the ticking of a clock, situated on the rear wall of 
the set, was to be the only sound heard. The question was im- 
mediately asked what should be used to imitate the clock. The 
obvious answer is the clock, since it is difficult to get any other 
instrument to sound more like the clock than the clock does. 
The scene was recorded, using the clock as the source of sound, 
with the microphone in the normal dialogue position for the 
action, and a very successful sound record resulted. 

In view of the stress that has been laid on the necessity of 
sets having more sound reflection than those previously in use, 
it might be of interest to consider why some of the sets of the 
past have given what is commonly called a “tubby” quality. 
There are two ways in which a set can cause the sound to persist 
in it for a short time after the source has stopped. The first 
of these methods is by reflection of sound from the walls and 
floors and this method is the only one which should be active to 
any extent. The second method is by a diaphragm action of the 
walls. In this case the sound sets the walls into vibration, and 
they continue to vibrate for a short time, thereby causing sound 
after the original source has stopped. This type of “hang- 
over” usually has a decided frequency characteristic and is 
highly objectionable. 

In the earlier sets, the spacing of the studding, and other 
supports for the set-wall material, was so great that the natural 
periods of the wall sections occurred in the same frequency 
region as the fundamental tones of the average male voice. 
This resulted in an accentuation of the low pitched frequencies 
of the voice, without a corresponding accentuation of the higher 
frequencies, which higher frequencies are responsible for both 
the crispness and articulation. To make matters still worse, 
where the sets were heavily draped, the damping material 
usually absorbed these high frequencies more efficiently than the 
lower ones. 

With these early sets, which were designed in such a man- 
ner that they accentuated the low frequencies, and removed, by 
absorption, the high frequencies, it was practically impossible to 
record highly intelligible speech unless the speaker faced ap- 
proximately toward the microphone. With the liver sets recom- 
mended, if the high frequencies, particularly those which carry 
the hissing sounds, fail to reach the microphone directly from 
the speaker’s lips, they do succeed in reaching it by reflection 
from the walls of the set. It is, therefore, possible with these 
sets to record intelligible speech, where the speaker is facing 
directly away from the microphone position. 

One interesting fact in connection with the use of the 
technic described is that the pictures recorded by it, are not run 
too loud in the theatre. This probably results from the fact 
that the reproduction is easily and comfortably understandable 
at the back of the theatre, without excessive loudness. 

There is one more important point to stress. Except under 
very unusual conditions, the mixer dials should be set at the 
beginning of the take and not touched thereafter. In other 
words, the record should be made with the volume ranges de- 
manded by the scene being depicted. This rule applies to more 
than 90% of the recording required for pictures. 

Any one who has done much mixing will realize the discom- 
fort of complying with this rule, because of the natural tendency 
to twist the dials. Someone has facetiously nicknamed this 
tendency “mixer's itch.” Probably the best way to overcome it 
is to continue to twist the dials, but limit the amount of twisting 
to about 3 db. Since 3 db is scarcely noticeable to the ear, it 
does no damage to the overall artistic result and is therefore 
permissible. After the mixer has become accustomed to limiting 
the twisting to 3db, he can then remember that since 3 db is 
hardly noticeable to the ear. this amount of mixing not only 
does no harm, but also does no good and therefore is unneces- 
sary. In view of the fact that most of the recording does not 
require mixer manipulation, it seems unfortunate that it is 
necessary to appear to lay any stress on the exceptions by enum- 


erating a few. However, it is necessary from certain practical 
considerations to occasionally control the volume during record- 
ing. An instance of this is as follows: when two actors, playing 
opposite one another, have very different voice intensities, it is 
legitimate to have one volume setting for the weaker voiced 
speaker and another for the louder voiced speaker. This technic 
should only be used when the speakers’ voices differ sufficiently, 
so that they would be unsuitable from the standpoint of the 
legitimate stage. A second example would be the case of very soft 
dialogue of long duration occurring within a scene. It is then 
advisable to raise the level of this slightly, to avoid the danger of 
its being interfered with by surface noise after the prints be- 
come old. Other similar situations would naturally be handled 
in a similar manner. This rule might be restated as: Never 
touch the mixer dials during a take unless there is an important 
artistic reason for the resulting unnaturalness. 

The final matter is scoring. Scoring is normally divided 
into two parts, pre-scoring and post-scoring. Pre-scoring refers 
to the condition where the sound record is made first, and the 
scene photographed synchronously with the playing of this 
record. The acoustics of pre-scoring should be designed to fit 
the acoustics that would be expected in the scene which is to be 
depicted with the sound record, and therefore each case is a prob- 
lem of its own. However, the principles governing the acoustics 
for this type of scoring are similar to those for sets. 

In general, pre-scoring is best limited in incidental music, 
music for dancing, marching or for other off stage sounds. It 
is difficult to pre-score a song in which the singer appears in a 
close-up or semi-close-up in the picture, since it has been found 
that the singer pays more attention to keeping in synchronism 
with the record than to acting. It is, therefore, preferable under 
these conditions to make a direct synchronous take. 

Post-scoring is the addition of music and occasionally dia- 
logue to a scene which has already been photographed. The 
greater part of post-scoring is done in a room or studio known 
as a scoring stage, the acoustics of which can be adapted to the 
requirements of this type of work. The two important acoustic 
factors controlling such a stage are first, its time of reverberation, 
and second, the distribution of sound absorbing, and sound 
reflecting material within it. It is well known that for two ear 
listening, the time of reverberation of a room for music depends 
upon the size of the room. This is also true for one ear listen- 
ing or recording, with the difference that the numerical value of 
the time is less than for two ear listening. 

The method of obtaining any given time of reverberation 
within a room is completely described in Watson’s “Acoustics of 
Buildings.” 

The distribution of the damping is shown approximately in 
Fig. 6. It should be noted that this is an attempt to artifically 
reproduce natural listening conditions, namely, the music is re- 
produced in the live end, which would correspond to the stage of 
an auditorium, and the microphone is placed in the comparatively 
deader end, which would correspond to the audience position. 
The listening end of a room in an auditorium is not ordinarily 
damped artificially, because the clothing of the audience consti- 
tutes very effective absorbing material. 

The adjustable damping shown in Fig. 7, is for two pur- 
poses: First to compensate for orchestras of different numbers 
of musicians, and second, to control the time of reverberation, 
so that it lies in the desired region as shown in Fig. 6. Ap- 
proximately 4 sq. ft. of rock wool 2 inches thick is equivalent in 
damping, to the clothing of one musician. 

There are probably many arrangements of the orchestra 
players, which will give highly satisfactory results. Consider- 
able experience has failed to disclose an arrangement which is 
superior to the natural arrangement which the musical director 
would choose, were he giving a concert in a small auditorium. 
In view of the fact that it is often necessary to photograph an 
orchestra while playing, this natural arrangement, which is 
satisfactory from a visual standpoint, as well as a musical one 
seems desirable. It should also be noted that with such a natural 
arrangement, no special experience is required on the part of the 
musical director. Samples of orchestra recording, made with 
this type of arrangement, can be listened to by purchasing any 
of the symphony orchestra records made in this country by the 
Victor Talking Machine Company, and issued since the summer 
of 1927. 

In scoring, as in ordinary dialogue recording, the dials

Technic of Recording Control 

(Continued from Page 18) 

materials as nearly as possible, and in particular should be 
braced sufficiently so that they do not tend to materially partake 
of the vibrations set up in the air by the sound. 

When a set has been designed in this manner, experience 
has shown that the incidental noises sound more realistic and 
convincing, and that they may usually be recorded at the time 
the original scene is taken. In one picture, on which this technic 
was used, some dramatic scenes occurred which were to be in- 
tensified by a period of sudden silence. In order to accentuate 
the silence, the ticking of a clock, situated on the rear wall of 
the set, was to be the only sound heard. The question was im- 
mediately asked what should be used to imitate the clock. The 
obvious answer is the clock, since it is difficult to get any other 
instrument to sound more like the clock than the clock does. 
The scene was recorded, using the clock as the source of sound, 
with the microphone in the normal dialogue position for the 
action, and a very successful sound record resulted. 

In view of the stress that has been laid on the necessity of 
sets having more sound reflection than those previously in use, 
it might be of interest to consider why some of the sets of the 
past have given what is commonly called a “tubby” quality. 
There are two ways in which a set can cause the sound to persist 
in it for a short time after the source has stopped. The first 
of these methods is by reflection of sound from the walls and 
floors and this method is the only one which should be active to 
any extent. The second method is by a diaphragm action of the 
walls. In this case the sound sets the walls into vibration, and 
they continue to vibrate for a short time, thereby causing sound 
after the original source has stopped. This type of “hang- 
over” usually has a decided frequency characteristic and is 
highly objectionable. 

In the earlier sets, the spacing of the studding, and other 
supports for the set-wall material, was so great that the natural 
periods of the wall sections occurred in the same frequency 
region as the fundamental tones of the average male voice. 
This resulted in an accentuation of the low pitched frequencies 
of the voice, without a corresponding accentuation of the higher 
frequencies, which higher frequencies are responsible for both 
the crispness and articulation. To make matters still worse, 
where the sets were heavily draped, the damping material 
usually absorbed these high frequencies more efficiently than the 
lower ones. 

With these early sets, which were designed in such a man- 
ner that they accentuated the low frequencies, and removed, by 
absorption, the high frequencies, it was practically impossible to 
record highly intelligible speech unless the speaker faced ap- 
proximately toward the microphone. With the liver sets recom- 
mended, if the high frequencies, particularly those which carry 
the hissing sounds, fail to reach the microphone directly from 
the speaker’s lips, they do succeed in reaching it by reflection 
from the walls of the set. It is, therefore, possible with these 
sets to record intelligible speech, where the speaker is facing 
directly away from the microphone position. 

One interesting fact in connection with the use of the 
technic described is that the pictures recorded by it, are not run 
too loud in the theatre. This probably results from the fact 
that the reproduction is easily and comfortably understandable 
at the back of the theatre, without excessive loudness. 

There is one more important point to stress. Except under 
very unusual conditions, the mixer dials should be set at the 
beginning of the take and not touched thereafter. In other 
words, the record should be made with the volume ranges de- 
manded by the scene being depicted. This rule applies to more 
than 90% of the recording required for pictures. 

Any one who has done much mixing will realize the discom- 
fort of complying with this rule, because of the natural tendency 
to twist the dials. Someone has facetiously nicknamed this 
tendency “mixer's itch.” Probably the best way to overcome it 
is to continue to twist the dials, but limit the amount of twisting 
to about 3 db. Since 3 db is scarcely noticeable to the ear, it 
does no damage to the overall artistic result and is therefore 
permissible. After the mixer has become accustomed to limiting 
the twisting to 3db, he can then remember that since 3 db is 
hardly noticeable to the ear, this amount of mixing not only 
does no harm, but also does no good and therefore is unneces- 
sary. In view of the fact that most of the recording does not 
require mixer manipulation, it seems unfortunate that it is 
necessary to appear to lay any stress on the exceptions by enum- 


erating a few. However, it is necessary from certain practical 
considerations to occasionally control the volume during record- 
ing. An instance of this is as follows: when two actors, playing 
opposite one another, have very different voice intensities, it is 
legitimate to have one volume setting for the weaker voiced 
speaker and another for the louder voiced speaker. This technic 
should only be used when the speakers’ voices differ sufficiently, 
so that they would be unsuitable from the standpoint of the 
legitimate stage. A second example would be the case of very soft 
dialogue of long duration occurring within a scene. It is then 
advisable to raise the level of this slightly, to avoid the danger of 
its being interfered with by surface noise after the prints be- 
come old. Other similar situations would naturally be handled 
in a similar manner. This rule might be restated as: Never 
touch the mixer dials during a take unless there is an important 
artistic reason for the resulting unnaturalness. 

The final matter is scoring. Scoring is normally divided 
into two parts, pre-scoring and post-scoring. Pre-scoring refers 
to the condition where the sound record is made first, and the 
scene photographed synchronously with the playing of this 
record. The acoustics of pre-scoring should be designed to fit 
the acoustics that would be expected in the scene which is to be 
depicted with the sound record, and therefore each case is a prob- 
lem of its own. However, the principles governing the acoustics 
for this type of scoring are similar to those for sets. 

In general, pre-scoring is best limited in incidental music, 
music for dancing, marching or for other off stage sounds. It 
is difficult to pre-score a song in which the singer appears in a 
close-up or semi-close-up in the picture, since it has been found 
that the singer pays more attention to keeping in synchronism 
with the record than to acting. It is, therefore, preferable under 
these conditions to make a direct synchronous take. 

Post-scoring is the addition of music and occasionally dia- 
logue to a scene which has already been photographed. The 
greater part of post-scoring is done in a room or studio known 
as a scoring stage, the acoustics of which can be adapted to the 
requirements of this type of work. The two important acoustic 
factors controlling such a stage are first, its time of reverberation, 
and second, the distribution of sound absorbing, and sound 
reflecting material within it. It is well known that for two ear 
listening, the time of reverberation of a room for music depends 
upon the size of the room. This is also true for one ear listen- 
ing or recording, with the difference that the numerical value of 
the time is less than for two ear listening. 

The method of obtaining any given time of reverberation 
within a room is completely described in Watson’s “Acoustics of 
Buildings.” 

The distribution of the damping is shown approximately in 
Fig. 6. It should be noted that this is an attempt to artifically 
reproduce natural listening conditions, namely, the music is re- 
produced in the live end, which would correspond to the stage of 
an auditorium, and the microphone is placed in the comparatively 
deader end, which would correspond to the audience position. 
The listening end of a room in an auditorium is not ordinarily 
damped artificially, because the clothing of the audience consti- 
tutes very effective absorbing material. 

The adjustable damping shown in Fig. 7, is for two pur- 
poses: First to compensate for orchestras of different numbers 
of musicians, and second, to control the time of reverberation, 
so that it lies in the desired region as shown in Fig. 6. Ap- 
proximately 4 sq. ft. of rock wool 2 inches thick is equivalent in 
damping, to the clothing of one musician. 

There are probably many arrangements of the orchestra 
players, which will give highly satisfactory results. Consider- 
able experience has failed to disclose an arrangement which is 
superior to the natural arrangement which the musical director 
would choose, were he giving a concert in a small auditorium. 
In view of the fact that it is often necessary to photograph an 
orchestra while playing, this natural arrangement, which is 
satisfactory from a visual standpoint, as well as a musical one 
seems desirable. It should also be noted that with such a natural 
arrangement, no special experience is required on the part of the 
musical director. Samples of orchestra recording, made with 
this type of arrangement, can be listened to by purchasing any 
of the symphony orchestra records made in this country by the 
Victor Talking Machine Company, and issued since the summer 
of 1927. 

In scoring, as in ordinary dialogue recording, the dials 
should be operated as little as possible during a take. With or-

At Last It Is 
Possible! 

For many years Directors and Camera 
Men have desired special effects in their 
films after the sets have been shot and dis- 
mantled^ or it is too late or too expensive 
to make a retake. Such effects as making 
a long shot into a close-up, putting in lap 
dissolves and fades, making a miniature of 
a scene and double exposing it over 
another scene, and other special effects. 

To meet this situation, the Burton Holmes 
Laboratory has installed one of the new 
DEPUE 35 mm. Optical Printers which 
will do all of the above stunts and many 
more. 

Keeping abreast or ahead of the times has 
always been the policy of this organiza- 
tion.

Voice Test 

(Continued from Page 13) 

Nicht Wahr? .... Ja, ja, it is this time a speaking test only 
to be. If she can not sing — pfui ! There are always doubles! 
How soon are you ready.? .... So soon as I am? Wunderbahr! 
I am ready when Mr. Westman the lady has made up ... . Ach, 
here she comes now!” 

“John Smith” went on up to the monitor room. It was a 
bare, drab little place, but he loved it. It was his. His domain. 
His temple — the inner sanctuary from which he controlled the 
entire mystery of the recording machinery. Three bare, plastered 
walls, and a fourth wholly filled with great, plate-glass bay- 
windows through which he could survey the entire stage. Close 
by, his throne and altar — an office chair and a plain table covered 
with the mysterious controls of the system. Here, indeed, he 
wielded a godlike power: here he sat in judgment over the 
words of those below. A twist of the wrist, and they were 
recorded for all time. Another twist, and they were cut off, 
if he chose, in mid-phrase, or the words so terribly mutilated 
that none might understand them. What mortal could wield 
a more vast, unseen power over the words, the acts — even the 
very lives and careers of his fellow creatures? 

But enough of such romancing. The set was being lit up, 
the great, sound-proof doors closing: things must be about 
ready down there. He, too, must be prepared. He phoned the 
recording-room. Yes, they were ready, cameras loaded, waxes 
in place, all ready to turn over. He reached for the switch that 
controlled the power. He closed it. 

Suddenly, startlingly, a voice boomed from the loudspeaker 
beside him: ”. . . . remember. Honey, this is the one big chance 
for both of us. If your test is all right, you’ll get the part, 
and you're .... we’re made. If you don’t — we’re sunk. 
Remember, it’s our last chance, since the market hit you so ... . 
our last chance. It’s your turn, now, to pull us both out of the 
hole just as it was mine back East, when I rid you of . . . .” 

“Smith” hastily switched off the power. Herb had left the 
mike on that little set switched in. Yes, down there he could 
just see a tiny, golden-headed figure in earnest conference with 
a tall, shabby-looking man .... Must be the girl Steinberg 
was testing .... and her husband .... or lover. Rotten trick, 
going on like that just before a test .... Beastly thing, any- 
way, saddling a woman with your troubles .... bad enough 
to stand by and let her pull you out .... but to beg her to 
.... God! What a cad. Why couldn’t he be a man .... shield 
her .... protect her .... give her what she needed .... 
what she wanted .... make her happy . . . .or — get out? .... 
How could a man be so low as to drag a girl like that down 
with his own failure .... How could he ... . ? 

He carefully switched out the offending microphone, then 
turned the power on again. He cut the main circuit in. There, 
that was better! Things were coming through perfectly. He could 
hear the director’s voluble instructions to Dick Miller, the 
crackle of a cold lamp just turned on, the low, quiet voice of the 
script girl — everything as it should be. It would be a fine 
record. Well, he’d do all he could to help that poor child to 
success. He’d do his part to make up for the burden her lover 
imposed upon her .... He could do a lot, too, with such fine 
equipment, all at its best .... not like Herb’s fool mike. 
Wouldn’t do to test her with that .... it would ruin every- 
thing He wondered if Herb had improved it any. Well, 

there was time to listen through it, and see. He threw the 
switch that controlled it ... . Lord! How it changed things! 
He could just barely understand Dick, who was too far from 
the mike .... but when that script-girl spoke again — what a 
change it made in her voice! Made it all bassy and unin- 
telligible It would never do to use a mike like that when 

they were testing the poor girl Hastily he switched back: 

he made a mental note — it was the third switch .... mustn’t 
forget 

The phone buzzed. That would be Steinberg’s assistant 
calling to see if all was ready. “Hello. . . . Yes, sound is all 
ready . . . . O. K.” 

The loudspeaker shrilled to the note of the head gaffer’s 
whistle. Lights flooded the set. The babble of voices hushed. 
“Everybody quiet, please,” shouted the assistant. “Microphone 
rehearsal. All right, Mr. Steinberg.” 

Then Steinberg’s voice, soothing, coaxing. “All right. Miss 
Daingerfield. We’re ready. Joost read those lines I gafe you 
yesterday to learn. Ja — you know, where you are telling your 
neglectful husband you must leaf him.”

her voice were poor — if it only recorded badly .... like the 
script girl’s through Herb’s trick microphone .... Herb’s

connected! A twist of the switch — that third switch — a turn 
of the wrist — and the worm could turn. It was not too late! 
It was not too late! 

The telephone buzzed. Rehearsal must be over. He raised the 
instrument to his ear. 

“Hello?” 

“Halloh, Vas that not goot, yes? .... So! Is everything 
for shooting ready now? Fine!” 

Dimly through the loudspeaker came the clang of the gong. 
“Quiet! Quiet everybody — this is the picture!” 

Then came another voice: “All right, give us an interlock.” 

His fingers worked among the instruments before him. A 
red light flashed in the camera booths. 

“All ready. Turn ’em over!” 

More commands flowed from his busy fingertips. Another 
light glowed in the booths. The motors on cameras and re- 
corders began to purr. 

Through the speaker came a call: “Motors up to speed! 
Let’s go — they’re sinking!” 

He reached for the third switch.

JWo vie Alak ing; 


H 





By William Stull, A. S. C. 


AS SPRING again comes to us, and brings summer once 
more into sight, many amateur cameras that were little 
/ m used during the winter are being dusted off and pre- 
pared for another summer of happy filming. And as 
their owners look forward to their summer’s activities, the 
prospect of individual dramatic filming is becoming more and 
more enticing to many of them. But some who might like to 
try such work hold back. Perhaps they are terrified at the 
apparent immensity of the task; perhaps they feel that they 
don’t know just how to go about it: at any rate, they deny 
themselves a great deal of pleasure thereby. 

The cinematography of the amateur dramatic production is 
in no way different from the sort that most experienced ama- 
teurs are already accustomed to doing; the chief difference is 
the fact that a dramatic film cannot be a one man show. It 
requires the serious, concerted efforts of several people if it is 
to succeed. Secondly, this concerted effort must climax care- 
ful, detailed preparation. A picture may perhaps be made with- 
out preparation, but it can not be made efficiently and success- 
fully without it. Professional film people found that out long 
ago, and "shooting from the cuff” has accordingly been tabu 
for many years. Today more time is often spent on the prep- 
aration of a picture than on the actual camerawork, so that 
when the shooting commences, every move is known and ar- 
ranged for in advance. 

The amateur can do no better than to follow this example. 
Why shouldn’t he be prepared, when he has quite enough 
technical and artistic handicaps to overcome already? Of course, 
in personal film work there must always be a certain amount 
of impromptu shooting, but in organized dramatic work, 
and wherever else it is at all possible, the amateur should work 
from a definite plan. This plan may be merely a mental outline, 
or it may be a detailed, written script: but a plan there should 
be. 

In the cases where a definite, written script is possible, this 
script should be prepared as far in advance as is feasible, and 
be made as complete as possible. The script should grow out 
of a brief synopsis of the plot, or action. This is the scenario 
itself. Then, once this action has been definitely perfected and 
approved by all concerned, the synopsis should be enlarged to 
form a shooting continuity (commonly called a working script) 
This is literally a written word-blueprint of the picture as the 
camera will see it. It should specify every scene, giving the 
number of the scene, the estimated footage, the camera set-up. 
the angle, the action, and the type of location. Spoken titles 
should be included in the script, so that the actors may know 
what words to speak when making the corresponding scenes. 

Before starting the camerawork, there are several definite lists 
which should be made up, as without them much confusion 
and loss of time and effort will result. First there is the list 
of the locations upon which the scenes will be filmed. The lo- 
cations should be selected in advance, and listed with the scenes 
to be taken at each, and with the people needed at each. It 
is also well to note the time of day when the light is right 
for each scene on this schedule. Then there is the property 
schedule, which again enumerates the scenes, and lists the 
"Props” needed in each. Any inanimate object used in a 
scene is a Prop whether it be a Rolls-Royce or a can of 
fishing-worms. In some cases, certain photographic accessories 
might well be on this list, too. Such a list is vitally important 
to the chief Property Man, if his very important work is to 
be done efficiently. 

When the picture is being photographed, it is wise to have 
one individual whose time is exclusively dedicated to keeping 
track of every detail of the action of the scenes photographed. 
This person is called the Script Clerk, and the job is far from 
being a lowly one, for it is highly important, and involves a 


tremendous amount of detail. In making a picture, scene 26, 
showing the hero leaving his room, may be shot today, while 
scene 2, showing him leaving the house, may not be photo- 
graphed until a week later; if there is no lynx-eyed script- 
clerk to check up on him, he may leave his room in perfect 
morning costume, with spats, gloves, and a cane, only to leave 
the house — apparently ten seconds later — in flannels and a 
tennis-racquet. Such things are constantly watched in profes- 
sional pictures, but even so, mistakes sometimes occur: Emil 
Jannings, for instance, once grew a very bushy head of hair 
apparently overnight! Even more remarkable mistakes have 
been known to occur in amateur films, so the script clerk is 
almost as important as the director or cinematographer. Besides, 
this detailed notation is a tremendous aid in keeping entrances 
and exits from becoming "crossed”, and in editing and titling 
the film afterwards. 

Each scene bears a number on the script; that number should 
be photographed on the film after the scene is made. In the 
studios this is done by holding up a slate in front of the camera 
while a few feet of film are ground off. This slate bears the 
number of the scene and "take” in moveable letters, the names 
of the director and the cinematographer, and the name of the 
picture. On the back of the slate is painted the self-explanatory 
legend, "N, G.” If the scene is good, one side of the slate 
is photographed; if it isn’t, the other side is used. For ama- 
teur use, in place of such slates there are a number of useful 
devices made, best among which are the scene-numbering note- 
books made by Bell U Howell and Eastman. These will carry 
all the information needed, yet they fold up to pocket size. 
They form a valuable written memorandum of the scenes and 
their contents for future use, and the numbers are the only quick 
method of identifying the scenes in editing. 

Now, do you think that the use of a prepared script will 
stifle inspiration and originality. Far from it; a prepared 
script is intended more as a guide than as an iron-clad sched- 
ule. It is to show what is needed, and how to get it in the 
quickest time, and to prevent one’s shooting ten scenes for a 
spot that will only accommodate one. True originality should 
have mixed with it enough intelligence to be able to distinguish 
between a guide and a shackle. The sort of "genius” which 
has to shoot a hundred reels to make one perfect one has no 
place behind a movie camera. There — particularly in the ama- 
teur field — the goal should be efficiency: knowing what is 
wanted before starting, and then the ability to get it with 
neatness and dispatch. 

However, don’t be fooled into thinking that working hast- 
ily is working efficiently. The deft speed that is born of 
practice is far different from the slipshod speed engendered by 
a desire to rush a scene through. Each person has his own 
most efficient working-speed: learn yours, and adhere to it 
under every condition. It is not the impression you make on 
the people watching you take your picture that counts, but the 
impression your work makes on the film! If you would always 
make good pictures — dramatic or personal — first, know your 
camera; then, know yourself. Then, dare to be yourself — 
and you cannot fail.

the human eye. Specific exposure may be obtained for 
high lights or shadows or average light. 

Other models available shortly 
for B. & H. Standard Cameras, 
Eyemo, still cameras and other 
types of motion picture cameras. 

The Photometer utilizes a well known photometric 
principle — direct comparison of the brightness of the sub- 
ject to be photographed with the brightness of a slender 
incandescent filament. This filament runs through the 
Photometer eyepiece, across the field of vision. You sight 
on your object, vary the brightness of the filament to match 
the brightness of the object . . . and you have your reading. 

The scientific principle upon which the Photometer is 
based guarantees the accuracy of the exposure readings 
and makes it invaluable to all cinematographers. 


The new B&H Filmo All-Metal TRIPOD 


The new B&H Tripod is easily the most rigid and steady 
of its kind ... an ideal professional-type tripod for Eyemo 
and Filmo owners. It is built with tubular extension legs 
and with simple means of locking them into position. The 
swivel head is an integral part of the legs, and has a self- 
compensating tilt mechanism which prevents the camera 
from tipping over and falling. A live spring retards the tilt, 
holding the camera firmly in neutral upright position when- 
ever the guide-arm is unlocked. When in use, the camera 
is tilted with ease, and when pointed at the object by the 
aid of the guide-arm is locked in position by a twist of the 
wrist. The head "pams” with frictionless ease and evenness. 
Price $36.00. See your Filmo dealer or write for literature

Big Merger of Hollywood Concerns 
in Amateur Field 

W ITH 1 6 millimeter motion pictures developed from a 
toy into a world-wide industry, and with business in 
general tending toward consolidation, the merger of the 
Centaur Film Laboratories, Inc., Cine Art Productions, Inc., and 
the Hollywood Movie Supply Company, all of Hollywood, 
whose activities have pertained to the 1 6 millimeter motion pic- 
ture industry, into Hollywood Film Enterprises, Inc., has just 
been consummated. This will make one of the largest organiza- 
tions of its kind in existence today. 

The new organization will reach out into the many branches 
of the 1 6 millimeter field and is planning many things for the 
future development of the industry. Simultaneous with the an- 
nouncement of the consolidation is the announcement of cine 
Voice, “the voice of home movies,” a portable home talking 
picture attachment Hollywood Film Enterprises, Inc., is putting 
on the market. 

This device, which will attach to any 1 6 millimeter motion 
picture projector or any portable 35 millimeter projector, has 
been carefully planned and built according to the specifications 
of sound engineers of the professional motion picture world. 
It plays sound-on-disc talking pictures recorded either at the 
standard professional speed of 33J/3 revolutions of the turn- 
table per minute, or at the standard phonograph speed of 78 
revolutions per minute. 

Along with the announcement of cineVoice also comes the 
announcement of the first films of a series of full reel feature 
talking pictures for the home recorded at the professional speed 
of 331/3 • 

Sound recording studios are being prepared by Hollywood 
Film Enterprises, Inc. Under one head will be a complete pro- 
duction unit with every facility for the making of both sound 
and silent pictures for entertainment purposes, these films being 
released exclusively in 1 6 millimeter, and also for the produc- 
tion of industrial and advertising films. A complete production 
staff will devote full time to the making of these last two types 
of pictures in both 35 and 16 millimeter. 

This merger brings into co-operation with this producing 
unit a distributing organization which is known throughout 
the world as the distributor of Cine Art 1 6 millimeter motion 
pictures for the home, and also one of the finest and most com- 
plete laboratories devoted to 1 6 millimeter films there is today. 
The laboratory is also doing developing and printing for some 
of the foremost motion picture producers in Hollywood. The 
unit which was formerly the Hollywood Movie Supply Com- 
pany, will continue as a retail distributor of motion picture 
equipment in and around Hollywood, California. 

Hollywood Film Enterprises, Inc., as well as taking over the 
parent companies, will continue to maintain the branch offices 
established by Cine Art Productions, Inc., in Chicago and New 
York. These offices will be direct branches of Hollywood Film 
Enterprises, Inc., for the marketing of Cine Art 16 millimeter 
films and cineVoice, and for the making of industrial pictures, 
both silent and sound, with a production staff available at each 
of these offices. 

The New York office, located at 6-8 East 46th Street, will 
be in charge of Mr. Harry S. Millar, who has been with Cine 
Art Productions, Inc., for the past two years. Mr. John J. 
Mertz, who has been with Cine Art Productions, Inc., in Chi- 
cago during the past year, will be in charge of the Chicago office, 
located at 109 North Wabash Avenue. 


Linguistic Difficulties 

A CCORDING to American Consul Samuel T. Lee, Lisbon, 
^ Portugal, the explantions of all films in Portuguese territory 
must be written in idiomatic Portuguese. There are no regula- 
tions regarding sound films but since the Government is a 
dictatorship a single decree of the appropriate ministry will 
suffice. It is understood unofficially that musical portions of sound 
films will probably be permitted in foreign languages but not 
dialogue. Spanish is the only foreign language generally under- 
stood though the patrons of the best cinemas know considerable 
French. 


A message from the Committee of the International Film 
Congress, in Brussels, states that according to announcements re- 
ceived up to now, 20 nations will be represented at the Congress 
next month.

Exposure ^.^eter Introduced 
"By "Bell and Howell 


Distribution of “Photometer” to Start This Month 


T he Bell ^ Howell Company has announced 
another new product, which should be of 
tremendous interest to every user of 1 6 milli- 
meter cameras. It is a new exposure meter which is 
B called the B. H. Photometer. 

1 This Photometer is said by its manufacturers to 
1 “mark the greatest forward advance in exposure 
1 meters yet witnessed in the whole era of photog- 
ra raphy.” Distribution is scheduled to start the first 
of this month. 

i “Movie makers everywhere,” say the manufac- 

turers, “will welcome this instrument and its eli- 
mination of guesswork in determining exposures. 

I While experience sometimes develops a certain abil- 
§ ity to guess the correct diaphragm setting, most 
I amateurs are in despair when it comes to determin- 
I ing exposure by this ‘hit and miss’ method. This 
i new, compact. Bell Howell pocket exposure meter 
t will make possible instantaneous readings of almost 
I infallible accuracy. The operator can now be sure 
I of correct exposure on every shot.” 

^ “The B. frf H. Photometer is so sensitive,” say 

i the manufacturers, “that a person’s face, for ex- 

I ample, can be exposed for the particular effect de- ® Photometer 



sired. Dark areas and shadows can be exposed 
specifically — an unprecedented achievement.” 

According to the information supplied by Bell 
Howell, this Photometer, a product of the new 
Bell & Howell Engineering Development Division, 
is of an entirely new type. It is based upon a simple 
laboratory method of light intensity measurement. 
The light intensity, or brightness, of a small sur- 
face, in the instrument, furnished by the incandes- 
cent filament of a small electric light bulb, is made 
to match the brightness of the surface or subject 
to be measured. The brightness of the filament is 
varied or controlled by the simple operation of 
turning a dial. The direct comparison of the bright- 
ness of the filament with the brightness of the sub- 
ject, as viewed through the eyepiece of the Photo- 
meter, permits a quick and direct reading, taken 
from the dial, of the lens diaphragm opening to 
be used for the subject being photographed. 

“This new method,” continues the announce- 
ment, “is unique in that it permits finding the ex- 
posure while actually seeing the subject. This makes 
it possible to determine the exposure required to 
register shadow or dark details, or highlight or 
light area details, or to strike an average exposure

On with the 'Dance 


Larry Ceballos Teaches How to Dance by Means of Screen 


By Hal Hall 


T eaching prospective screen dancers how to dance for 
the screen by means of the screen is the unusual method 
which is being employed by Larry Ceballos, who is in 
complete charge of all the dancing and dancers for Warner 
Brothers and First National Studios in Hollywood. 

The Ceballos system was conceived one day when Ceballos 
was at a friend’s house and saw a 16 mm. picture in slow 
motion of a golfer showing the correct and incorrect manner 
of whacking the little white golf ball over the greensward. 
That gave Ceballos an idea which he immediately tried out with 
untold success. 

“At the start,’’ explains Ceballos, “it was quite a difficult 
task to get our dancers to do their stuff in just the proper 
manner for the screen. And then came this idea. Now it is easy. 
For there is nothing that shows one their defects quite so well 
as on the screen. 

“You see, I get some new dancers in. I show them just 
what the steps are for the particular number we are going to 
use in the screen play. They rehearse and we photograph them 
when they think they are beginning to get good. Then we 
take the dancers to the projection room and let them see them- 
selves. That is enough. Those who are good can see it. Those 
who are not can also see it. No need for lecturing then. They 
sec for themselves and there is no argument. 

“That is where the screen dancer has the advantage over the 
stage dancer today. On the stage the girls cannot tell how they 
look. They just do the best they can, and have to let it go at 
that. But here our dancers can take a look at themselves and 
sec how they are going to look to others. A decided advantage. 

“Then, too, this method gives us the opportunity to see just 
whether or not the dance will appear to advantage on the 
screen. We might think a certain dance is wonderful when we 
are looking at it with the girls or boys actually before us. But 


on the screen the rhythm may be all wrong. It may not register 
at all. With sound, the complications set in, especially if there 
is acrobatic or tap dancing. So we can find out at slight ex- 
pense if a number is going to go over on the screen or not.” 

Ceballos, whose whole career has been devoted to the dance 
art, believes that dancing will have a big influence on the screen; 
that it will even bring about an entirely new type of picture 
some time in the future, just as it has had its effect on the 
stage. 

“Not until the sound pictures came,” says Ceballos, “did 
the dance have very much to do with pictures. That was 
probably because of two reasons. Before sound the musical show 
type of picture did not mean so much, and also the sound of 
the dancers’ feet has a certain fascination that is irresistible. In 
the old days of the silent screen one always had a peculiar idea 
that perhaps the dancers were really not dancing when you saw 
them float about with no sound. Now it is different, and the 
dancing is becoming a big factor in pictures. 

“A musical comedy is not a musical comedy unless there is 
dancing. The more dancing the better the show as a rule. But 
I feel that we are going to have more than musical comedies 
with dancing. I feel certain that the future is going to see the 
dance playing a big part in pictures. It must. The dance is one 
of the very oldest of the entertainments, and it has its direct 
appeal to everyone. There is a certain grace and rhythm about 
dancing that appeals. It makes one forget the sordidness of this 
old world for a time, and wafts you away into a land of en- 
chantment where cares are forgotten and brings beautiful 
thoughts into troubled brains. 

“I can see in the future big pictures founded solely on the 
dance. The tempo of the picture will be governed by the 
dancing, and it will be a tremendous box office success. 

“Dancing has an excellent influence on the screen. Thou- 



Larry Ceballos’ girls at First National do not mind the snow.

Ceballos in action putting First National Chorus through its paces in preparation for a picture 


i< sands now see the best in dancing as compared to hundreds in 
jtthe past. The result cannot help but be for the good of the 

I ' whole. Peoples of the world are influenced in their choice of 
.clothing, furnishings, homes — practically everything — by the 
1 motion picture. And so it will be with the dance. Few of us 
( can sing, for we do not have the voices. But most everyone 
(can dance and the dances of the screen will influence the danc- 
1 ing of the screen patrons. It is inevitable. For that reason we 
( cannot be too careful about our dances. They must be of the 
' very finest and the best. We must watch carefully to keep out the 
• suggestive and the immoral. That must not be. In the future 
1 I look for the new dance steps to come from the screen. 

“And while on the subject of the screen’s contributing to 
; life in general, let me say that the time is coming, in my 

I opinion, when the stage will begin to draw its plays and musical 

shows from the screen. For years the screen has been taking 
stage plays and making them into pictures. The tables are going 
to be turned in the future. The greatest minds are being em- 
ployed by the picture companies. It stands to reason that even- 
tually the stage is going to be buying screen plays for stage 
presentation.” 

Ceballos has approximately a half hundred dancers on his 
regular staff at the studio. These are kept in vigorous train- 
[ ing daily. There is no let down at all. When they are not 

j rehearsing for a picture or playing in a picture the dancers are 

working out new steps and dances for future productions. His 
dance studio is one of the busiest spots on the studio lot. 

Motion Picture Film Visualizes Mining, Distri- 
bution and Utilization of Sulphur 

E HE mining, distribution and uses of sulphur, a mineral of 
great economic importance, are visualized in a new two-reel 
educational motion picture film just completed by the United 

I States Bureau of Mines, Department of Commerce, in co-opera- 
tion with a large producing company. 

The United States produced about 2.000,000 tons of sul- 
phur in 1929, or more than 80 per cent of the world total, a 

i * carload of sulphur being produced in this country every ten 
minutes, it is pointed out in the film. 

The early scenes show a typical sulphur mining town near 
the Gulf of Mexico in Texas, where mpst of the domestic sul- 
phur is mined. The highly ingenious process by which sulphur 
is mined, by melting it underground with heat supplied by 
superheated water, and then forcing the liquid sulphur to the 
surface by compressed air, is next illustrated. Views are given 


of the huge boilers for the generation of steam used for water 
heating and power and of the great reservoirs necessary for the 
insurance of adequate supplies of water. The treatment plant in 
which scale-forming minerals are removed from the water be- 
fore it enters the boilers and heaters is also shown. 

Wells are drilled down through various formations of the 
sulphur-bearing strata, and are equipped with concentric pipes 
which carry down the heated water and compressed air and 
bringing up the liquid sulphur. A series of views picturizes the 
drilling of the wells, in which ordinary oil well drilling equip- 
ment is used. A diagrammatic sketch of a cross section of a 
sulphur dome indicates the various strata of sand, clay, gumbo, 
limestone, calcite, and gypsum encountered in the drilling of a 
well. By the use of animated photography, every step in the 
process of the melting of the sulphur at a depth of 1,000 feet 
and the forcing of the liquid sulphur to the surface by com- 
pressed air is made plain. 

A series of scenes demonstrates how the liquid sulphur from 
the wells is piped to relay stations, then pumped to a main 
pumping station and elevated to the top of huge storage vats, 
where it cools and solidifies. The sides of these vats are built 
up to a height of 40 to 50 feet in sections, as needed, to hold 
molten sulphur in process of solidifying. Each vat contains more 
than 1.000.000 tons of sulphur. 

When a vat has reached the desired height the sides are re- 
moved and the sulphur is blasted for loading in shipment. A 
series of interesting scenes depicts the drilling of blast holes in 
the top of the huge vat, the firing of the blast, and the load- 
ing of the sulphur into railway cars. Four thousand pounds 
of sulphur are picked up at a time in the buckets of the power- 
ful hoisting machines used. 

The loading of the sulphur in ships at a Gulf port is next 
depicted. A big belt conveyer is used to put the sulphur aboard 
the boat, and the sulphur is weighed on the belt at the top of 
the incline. In 1929, nearly 800,000 tons of sulphur were ex- 
ported and more than a million tons were shipped to United 
States points, it is explained. 

Animated photography is again resorted to in demonstrating 
that a pile of 1,000,000 tons of sulphur, equal to the contents 
of one of the huge storage vats, is larger than the Capitol at 
Washington, D. C. 

The numerous important uses of sulphur are demonstrated 
also by the use of animated photography, a cube supposed to 
represent 1,000,000 tons of the material being chipped off into 
sections representing the amounts used for this purpose. Of

New Amateur Camera With 
Visual Focusing Finder 



'^HE Victor Animatograph Company of Davenport, Iowa. 

has just made an announcement that should be of great 
interest to all home movie makers. It is a new 1 6 mm. Cine 
Camera permitting direct visual focusing. This is the first in- 
strument of its kind to be equipped with a visual forcus finder, 
and marks a decided forward step in the 16mm. field. This 
camera is called the Model 5 Victor Cine Camera. 

The lens to be used is turned to the finder position, and by 
actually observing an image which exactly corresponds, as to 
size and focus with the one that will be exposed, each scene 
may be individually focused, without paying any attention at 
all to the focusing ring on the lens, except moving it, of course, 
to produce the sharpest possible focus. 

This focusing feature makes more practical than ever, the 
use of the very fast lenses, particularly the F. O. 99 Dall- 
meyer and any of the other lenses of exceptionally large open- 
ing. 

Also, it makes possible the accurate focusing of very close- 
up objects, even to within a few inches of the camera. This 
finder is in such position that it can be readily used on a tripod 
with the camera at eye level as well as when the camera is 
held in the hand. The focusing finder is very accurate. It 
registers exactly the same as the aperture. When the image 
has been focused, a one third turn of the turret brings the lens 
to operating position. 

Another feature of the MODEL 5 VICTOR CAMERA is 
that every essential operating speed is provided — 8 frames per 
second (half normal) — 16 frames per second, (normal) — 
24 frames per second, for making better pictures of rapidly 
moving objects, — 32 frames per second — and for SLOW-mo- 
tion, 72 frames per second, or 4J^ times normal. The op- 
erating button gives these additional speeds at a slight turn, 
and a lock-down operating position is provided for 8, 16, and 
24 frames per second. A non-operating lock position is also 
provided. 

The turret front is provided with three convenient knobs, 
for revolving the turret, without touching the lenses. All parts 
formerly nickeled are polished chrome plated and a number of 
minor mechanical refinements have been adopted. 


According to an article by Prof. Sucharodsk in “Berlin Am 
Morgen” (Berlin, Germany) , it will shortly be possible to give 
cinematographic lessons in the 150,000 schools in Russia, which 
are being equipped for projection.

Bell HowcH’s New Tripod 

'THE new Filmo All-Metal Tripod, which is announced 

for May 1, was developed to meet every requirement of 

the personal movie-maker. Telephoto as well as short shots 
can be made without risk of jerkiness on the film and the 

consequent lessening of the effectiveness of the projected pic- 
tures. The new tripod is a Bell Howell designed instrument, 
a product of this company’s new engineering laboratories. It 
has a standard tripod socket and hence can be used with any 
camera. 

The construction of this tripod is a radical departure from 
that of the usual light portable tripod for the amateur or 
semi-professional. It is remarkable for its rigidity, for its 
light weight and compactness, as well as for its unusually 

versatile performance and its convenience in use. 

It is provided with adjustable extension legs, with simple 
means of locking into position. Its swivel-head provides for 
every desired angle and camera movement. This head is an 
integral part of the legs and is dust-proof. 

An automatic tilting counter-balance is a distinctive fea- 
ture of this tripod. The counterbalance prevents the camera 
from pulling forward and tripping the tripod over. It also 
makes for smoother tilting, since it relieves the operator of 
much of the camera’s weight. The counterbalance spring in the 
center of the tilting spindle is of the correct strength to pro- 
vide balance for the Filmo 70 camera at any angle, and is also 
very helpful when using a lighter or heavier instrument, either 
motion picture or still camera. 

The tripod pams with ease and extreme evenness. A constant 
and even application of balanced friction prevents jerkiness 
on one hand and too great freedom on the other. The result 
is an extraordinarily smooth pam which is greatly enjoyed 
on the screen. It is this unique principle of applying balanced 
friction that has hitherto been so difficult to work out. 


Three Screen Companies Are Joined in Merger 
With the acquisition by the Motion Picture Screen Corp. of 
the manufacturing plant, assets, patents, processes, name and 
good-will of the Truvision Projection Screen Corp., now bank- 
rupt, three screen companies are brought together under one 
management. The other concern is the Beaded Screen Corp., 
with which the M. P. Screen has become affiliated.

ILcn Roos, A.S.C., Settles Down as Manufacturer 



Len Roos in the old days when he was a wanderer 


M ost wanderers usually settle down after a certain number 
of years. The reasons for such cessation of globe-trotting 
are many and varied, but in the case of Len Roos, well 
I known member of the American Society of Cinematographers, 
I the reason is one of the most unusual this writer has hit upon. 

Len for years wandered all over the face of the globe with 
I his camera, making news reel pictures, independent pictures and 
] pictures in strange lands for various big companies. You never 
know just where Len’ was going to bob up with his camera. 
I China, India, Borneo. Siam, Africa, South America — he was 
( everywhere. 

But a few months ago he landed back in Hollywood. No one 
( expected to see him here for more than six or eight weeks. 
I However, he is still here, and present indications are that he 
will probably be here from now on. 

The reason for Len’s arrival in Hollywood was to find some 
' sort of sound equipment that would be really portable and 
< could be carried around by a traveling cameraman and used in 
. any part of the world without the necessity of taking an 
t engineer and a force of helpers along. Len didn't find what 
1 he wanted, so he started creating such a device himself. The 
I result is the Tanar Corporation, Ltd., an organization manu- 
I facturing portable sound equipment that can I)e carried by a 
(Cameraman and his one assistant: an equipment that can be 
I placed in two grips and carted by hand, horse-back, mule-back 
( or wheelbarrow, and which can be set up for use in a few 
I minutes anywhere. 

Len’s idea at first was to build something like that for him- 
self, but he saw the possibilities in it and soon a company was 
I formed and now Len has just about forgotten the business of 
I being a cameraman for that of managing a manufacturing 
( concern. 

"I have an itching heel every now and then,” says Len, 
‘‘and I feel that some day I shall just pack up my camera and 
make one more trip. But with business as rushing as it is now 
and with orders piling in on me, I don‘t see when that day 
will come. There are so many other men who are clamoring 


for real portable equipment that I simply can't fail them. So 
I guess that last trip will have to wait for a while.” 

So that’s that. The wanderer has quit wandering. 


Sound-on-Film Device Developed by Pacent 

A new all-frequency method of sound-on-film recording. 

said to combine the best features of both variable area and 
variable density recordings now in use, has been developed by 
Pacent, it is announced by Louis Gerard Pacent. The heart of 
the new system is a revolutionary lamp. Other features include 
great reduction of background and extraneous noise, and it is 
claimed that, from the theatre standpoint, the new device repre- 
sents a great step forward in effecting lifelike reproduction. 


18 Cameras Being Added to Technicolor Fleet 

E ighteen new cameras, one of the largest individual cam- 
era contracts ever placed, will be added shortly to the fleet 
of 35 already doing service for Technicolor, it is announced by 
Dr. H. T. Kalmus. Less than a year ago there were only 9 
Technicolor cameras in existence. 


France 

T he president of the Council, Minister of the Interior, 
addresses on February 24, a letter to the Prefects of France 
and Algeria dealing with the use of non-flam film. The atten- 
tion of these officials is drawn to the fact that Pathe Rural and 
Cinelux projectors (the latter using Ozaphance stock) offer such 
guarantees of safety that authority may be granted to use these 
machines on premises which do not dispose of separate projec- 
tion cabins. Other safety regulations, however, namely those 
dealing with the premises, exits, etc., have to be rigorously en- 
forced as heretofore. 

A company entitled Societe Parisienne Cinematographique has 
been formed in Paris, its object being production, distribution 
and export of cinematographic films. The company has a cap- 
ital of 2,000,000 francs in 500 francs shares, of which 600 
will be handled to Mr. Georges-Friede, the founder. Mr. Friede 
will also receive 1,000 founder’s shares. 


Africa 

T he public in North Africa requires sound-films, states a 
trade paper. An American sound picture met with excep- 
tional success, in spite of the fact that the silent version was 
already known to the Algerian public, while others have also 
received successful exhibitions. All the first-run theatres of Oran, 
Fez, Rabat. Casabalanca. Tangiers, Sidi bel Abbes, are expected 
to be wired in the near future. Two cinemas in Tunis, one in 
Casabalanca. and one in Algiers already have American appara- 
tus. In addition there are three French-made installations in Fez 
and Casabalanca. A “flying” servicing unit has been instituted 
in North Africa by an American electric company. 


A new company, the Ondra-Lamac G. m. b. H., has been 
formed in Berlin with a capital of 20,000 marks. It will deal 
with the production and distribution of films, especially sound- 
films. Karl Lamac is to be the manager.

'€very million tons of sulphur, it is made clear that 10,000 tons 
- go into the making of the old-fashioned remedy of “Sulphur 
:and molasses.” Fumigating and bleaching, it is shown, would 
i.account for 12,000 tons, while spraying and dusting fruit and 
; vegetation would demand 32,000 tons. The rubber industry 
•would require 24,000 tons, while the explosives industry would 
consume 28,000 tons. Sulphur is essential in the manufacture 
of sulphide pulp, used in making various grades of paper, and 
,t::for this purpose 129,000 tons would be required. Chemicals 
|i'.' would account for 28,000 tons, miscellaneous uses for 13,000 
|i:.tons, and the manufacture of sulphuric acid would consume 
j"724,000 tons. A series of scenes shows the dusting of or- 
i:•chards and vineyards to protect fruit against damage by insects 
ivand scale, the use of sulphur in the making of wood pulp, and 
\ the operation of a sulphuric acid plant. 

i The numerous uses of sulphuric acid, which accounts for 
r practically three-fourths of the crude sulphur demanded by com- 
pmerce, are made clear by recourse to animated photography, a 
phuge tank containing sulphuric acid being tapped for smaller 
' ;tanks representing the use of the acid in the manufacture of fer-

'metallurgical processes. 

Copies of the film, “Sulphur,” are available for exhibition 
by schools, churches, clubs, business and civic organizations, 
miners’ local unions, and others. No charge is made for the use 
of the film, although the exhibitor is expected to pay transpor- 
tation charges. Applications should be addressed to the Pitts-

High Lights of German Film 
Situation 

By Douglas Miller 

Assistant Commercial Attache of the Motion Picture Division, 

U. S. Department of Commerce, at Berlin, 

T he last few months have been a period of change and 
uncertainty in German film circles. At this time there are 
certain main facts which stand out clearly and which should 
be borne in mind when considering future business in Germany. 

The German film situation is difficult at present because of 
the general economic condition of the country; the change from 
silent to sound pictures which has not yet been completed; the 
patent difficulties between the large electrical firms which have 
made it uncertain what apparatus could be installed in studios 
and theatres; the absence of foreign and particularly American 
talkies from the market; the fall in German film exports owing 
to the language and patent barriers on German sound pictures. 
Sound Patent Situation. 

The electrical concerns will probably settle their present 
patent dispute in the year 1930 on a basis which will provide 
an exchange of patents and complete interchangeability of films 
on the principal makes of German and American apparatus. 
This will allow all American film companies to send some of 
their sound pictures to Germany if they so desire. 

Contingent. 

The present import contingent remains as a fundamental 
principle of the GeI^man Government policy. Whether or not 
the Geneva agreement is ratified, the contingent remains in some 
form or other. If the agreement is not ratified, the situation re- 
mains as it is. If on the other hand, the agreement does come 
into force on June 30 this year the administration of the pres- 
ent import regulations will be* transferred to the Ministry of 
Education and the contingent system will continue as a matter 
of cultural protection rather than an import regulation. This is 
simply calling the thing by another name. There is no possibili- 
ty of a free film market in Germany. If the Geneva agreement 
goes into effect the legislative measures which are already pre- 
pared will be passed within a few days transferring the present 
film control to the Ministry of Education. It is proposed to 
continue present regulations in any case about as they now are. 

According to a written statement from the Film Commis- 
sioner there will be no special contingent on sound pictures or 
talkies as far as feature films are concerned up to June 30, 
1931, but the Commissioner expressly reserves the right to 
institute special import restrictions on sound, shorts. These 
proposed restrictions will probably be instituted in four or five 
months. 

If the electrical companies compose their difficulties and 
American talking pictures enter Germany in large numbers the 1 
German industry proposes to request the Government to in- | 
stitute special protective regulations against foreign talkies prob- 
ably sharpening the present contingent regulations which al- | 
ready exist. It has already been stated that these new regulations | 
could not take effect before June 30. 1931, but if American f; 
talkies enter this market in quantity no doubt such regulations S; 
will be made shortly after that date in time to cover the playing- 
ing season 193 1-1932. ! 

American Talkies. 

American dialogue pictures will not be able to bring very ; 
large receipts in the German market. Once the public here has i 
become accustomed to hearing talkies in their own language, it " 
is not likely that they will care to listen to an English dialogue , 
which few of them understand. Neither is there much probability jj 
that German language versions made in the United States will j 
be great successes in Germany. Even Germans who have been 
in the United States only a few weeks unconsciously change - 
their accent and manner of speaking so that it becomes notice- 
able when displayed before an audience in their own country. 

If American firms desire to exploit the German market in 
dialogue pictures they will have to make such pictures in some l-ji 
of the German speaking countries of Europe. Jl 

There still remains the possibility of obtaining satisfactory |r 
business in Germany on nondialogue pictures with silent films; p 
which are still taking up most of the playing time of the first 
run houses and arc shown exclusively in 95 per cent of all 
German theatres and in synchronized musical pictures with littlerE 
or no English dialogue carrying the story in German titles. R 
The German film industry is not going to be able to com- l(

tihree years behind in the manufacture of talking pictures and 
'have not yet begun on color. The companies here are unable 
to make the large financial expenditures which are necessary in 
I'order to keep abreast of the technical developments in the 
^American industry. 

.-American Production in Germany. 

It will be almost impossible for American firms to produce 
talking pictures in Germany suitable for the American or 
rforeign markets. Studios and equipment, actors, and experience 
iire not available here. If American companies desire to continue 
selling their sound product in Germany they must obtain 
.contingent right either by making distribution alliances with 
' German producing companies or they must produce inexpen- 
sive German films for the local market. These can be either 
sound pictures made for local distribution or silent pictures, 
which are still the best commercial proposition in Germany 
and Central Europe generally, owing to the small proportion of 
Liheatres which are wired. 

'Conclusion. 

The attitude of the American film companies toward Ger- 
-many should be the one of two things; either they decide to re- 
main out of this market permanently on account of the diffi- 
cculties set up by patent controversies, the contingent, the 
'language barrier, and the difficulty of recovering the cost of 
ifheir own distribution organizations, or they must decide to 
;come into Germany with such of their sound product as is suit- 
able here, in a small way and make what sales they can, pro- 
dducing inexpensive German pictures for contingent rights, if 
.necessary, but investing very much permanent capital in 
I Germany. 

If American film companies refrain from offering their pro- 
ducts in the German market this will continue to have a de- 
:pressing effect on the situation here and will be reflected in less 
>box office receipts of the theatres. Nevertheless, the local cx- 
nhibitors are still inclined to look at the situation from a na- 
tionalistic viewpoint and in the long run are apparently quite 
willing to get along with less profits in the hope of building up 

stronger German film industry. If American film companies 
ido not sell their product in Germany during the next year or 
two their place will be entirely taken by German and other 
foreign films and the German market will continue to exist with- 
out them. The longer they stay out of the market, the harder 
at will be for them to re-enter. 


Belgium 

iZ\T THE international film exhibition in Antwerp, scheduled 
to take place next summer, the film as a means of propa- 
iganda and publicity for trade and industry will play a leading 
role. Several large halls have been installed for the exhibition 
of publicity films. Permanent shows will be run during the 
exhibition, with free admission. Numerous industrial concerns 
:nave decided to participate in these shows with pictures illus- 
trating the life and work in their factories, and the manufac- 
turing of various products. Moreover, a number of films for 
travel propaganda, showing landscapes of various countries, 
■aistorical and artistic places, etc., will be exhibited. 


New Developing Machine Invented by Roy Hunter 
^ A NEW developing machine for negative and positive film, 
described as an improvement which greatly clarifies sound, 
has been invented by C. Roy Hunter, director of sound and 
'oead of the photographic division of Universal, and Robert 
^Pierce, superintendent of the laboratory at Universal City. It 
SIS said to have a capacity of 1,000,000 feet of film weekly. 
-Dther companies are considering adoption of the new method. 
Universal states. 


Spain 

.ACCORDING to trade press reports, Spanish producers are 
■ becoming active. Several features are under way. These 
are based on popular Spanish novels and feature well-known 
artists. One feature is starring the matador Nicanor Valalta. A 
new production and distribution company, “Selecciones Nunez,” 
bf Madrid, has released a sound-film entitled ‘‘Futvol, amor y 
xoros,” which had a very successful first-run. The first Spanish 
dialogue film, including songs and musical numbers of Guerrero, 
1 well-known composer, is scheduled for early release. 


The Dutch Government has ruled that the Board of Cen-* 
wrs shall have control of all sound in connection with motion 
'pictures, states a Hague message. Distributors must supply the 
-Censor with all sound films and discs for approval.

A. S. C. Member Photographs Shadow Bands 

(Continued from Page 15) 

Then the Clarks photographed the artificial shadow bands | 
under conditions of such perfect control that they immediately 
determined the following points; 

1. Negative best suited to show the delicate contrast; 

2. Aperture required for a uniform picture as the eclipse 
progresses to, through and away from total darkness; 

3. Standardized timing of the film, so that the computers 
at the observatory can calculate accurately the speed of 
the shadow bands as they sweep across the field of view. 

A unique timing device was found made to order in the pres- 
ent type of sound track film. It was simple for these skilled 
cinematographers to co-ordinate the photographic record of the 
eclipse with the sound track record of the voice of the astron- 
omer, who counted the seconds as he watched an astronomical 
chronometer during the period of the total phase. 

Nowhere else in astronomical history has so accurate a method 
of timing a phenomenon been possible. 

The artificial eclipse was created by turning the beams of the 
sunlight horizontally into the laboratory by a coelostat, mounted 
outside the building, passing the sun rays through a lens of 
known focus and bringing the sun image sharply onto a verti- 
cal screen of ground glass. 

By heating the air near the rays with a flame, imitation 
shadow bands were caused to chase one another across the 
ground glass screen. The camera was set up at a known dis- 
tance back of the screen. 

By computing the degree of illumination of the ground glass 
from the aperture of the fixed lens and the side of the sun’s 
image, the experiment was regulated to actual eclipse conditions. 

The most successful film of several makes and types tried, ^ 
proved to be Type 2, Eastman panchromatic. , 

This gave the clearest contrast and at the same time the best , 
illumination to the edges of the field. | 

The Bell and Howell camera was equipped with a Zeiss 3 -inch 
lens. ' 

The exposures averaged of 1 /60 second. 

From the eclipse record, now reposing in the archives of the ' 
Mount Wilson Observatory, Dr. Nicholson says he can deter- ‘ 

mine the width of the mysterious bands of light and shade that 
dapple all light-colored surfaces during an eclipse; the direction ‘ 
of their motion with relation to the direction of the sun’s angle: 
the speed of the bands and the relationship between their paral- ‘ 
lelism and direction of motion. 

“Astronomical science is extremely grateful to the Messrs. : f 
Clark and to the American Society of Cinematographers for i 
their gift of this film,” said Dr. Nicholson. j ' 

“Astronomers now learn with pleasure the cinematograph- | 
ers are men of scientific attainments, with ideals and aspirations. ' 
“Astronomy was enriched in 1846 by the application of 
photography to its old visual methods. Now, in 1930, 84' j. 
years later, the motion picture camera, scientifically used, has, 
again served to expand man’s concept of the universe in which; ^ 
he lives.” _ _ j 

The unusual feat of recording the scientific pictures with sound; ^ 
was also accomplished. The sound consisting of the astron-- 
omer’s voice counting off the seconds of the actual eclipse ass ^ 
it was being made. This gives a record that cannot be any-- 
thing but accurate. The Metrotone Newsreel furnished a crew, j 
of four men and two sound trucks for this, and the Fox stu-- 5 
dios, where Charles Clarke is employed, loaned Clarke for thee 
experiment. C 

/Is this magazine goes to press too early to have pictures of the experiment 
we make the announcement now that in next month's issue there Will be t p, 
pictures of the shadow bands, the first in history, as well as scientific , 
articles showing just what was accomplished for the advancement of science. '

Your Makeup Problems 



By Max Factor 

[Internationally Known Authority on Makeup] 


Dear Mr. Factor: 

I appear in amateur theatricals regularly and as a rule only 
play those roles to which I am adapted being a little stout and 
also have a double chin. Now I am asked to play a juvenile 
role as the party who was to play that role failed us and there 
is no one else available. Will you please tell me how to best 
conceal my double chin. I am blonde. 

F. B. Akron, Ohio. 

Answer: 

A double chin is shadowed by using dry rouge and blending 
carefully. It is also possible to do this by using a foundation 
three shades darker on the double chin than that used on the 
rest of the face, oi^you can shadow your face with a maroon or 
brown lining color. 

Dear Mr. Factor: ( 

Mascara hurts my eyes — will you please tell me of some 
other preparation which accomplish the same results, as mascara 
causes my eyes to water and smears up my make-up. 

C. C. Fla. 

Answer: 

Since all mascaras are soluble in water and your eyes are 
oversensitive and subject to. watering I suggest that you use 
Cosmetic. This preparation is made of wax with a very low 
melting point. Hold the cosmetic in a small container over 
heat until melted. Dip paper liner or orangewood stick into 
melted cosmetic and apply to the lashes, holding two or three 
lashes together by beading the tips. Repeat until they acquire 
the desired beaded appearance. The preparation is water proof 
and is readily removed with cold cream. 


Dear Mr. Factor: 

I have done stage work but only recently have I had an 
opportunity to appear on the screen. Make-up is very important 
and would you kindly give me my proper make-up for brunette 
with blue eyes and cream colored skin. 

S. E. New Rochelle, N. Y. 

Answer: 

Use Panchromatic Grease Paint No. 25 — Pancro, Face Pow- 
der No. 25 — Pancro Lining color No. 22 — Moist Rouge No. 
9 and dark brown Dermatograph pencil. 

Dear Mr. Factor: 

I am a drab type of blonde and would give almost all I 
possess to find a make-up which will absolutely fit me. I 
have blue eyes and a very fair skin. Looking forward with 
much interest to your reply. . 

S. O. B. 

Answer: 

Satisfaction with make-up depends entirely whether or not 
you are using a color harmony make-up, suitable to your com- 
plexion. Also you must be careful in the manner with which 
you apply the make-up after your color harmony problem 
has been solved. The tendency today is to use make-up which

German Color 

'^HE first German color-sound-film, “The Nun of Heiligen- 
"*■ worth,” is scheduled for release this month. The film is 
produced by “Detofa” (Deutsche Ton und Farben-Film G. m. 
b. H.), of Berlin, directed by Rolf Raffe, and is starring Liane 
Haid. Countess Larisch, former lady in waiting to Empress 
Elizabeth of Austria, is responsible for the scenario. 

According to a statement published by the Film-Kurier. there 
are 409 German cinemas, either wired or being wired for the 
reproduction of sound-films.

Technic of Recording Control I 

(Continued from Page 24) > 

chestras of 30 pieces or less, it is scarcely ever necessary to touch J 

the mixer dial during a take. However, with very large orches- j 

tras, a loudness range of 50 db is sometimes obtained, and this ! 

range is slightly too great to be handled with the present system. j 

It is, therefore, necessary to do some manipulation. There are 
two ways this compressing of the range may be handled. The 
first is to permit the volume to rise fairly close to over-load 
and then began cutting down on the volume control to avoid 
valve clash or the record cutting over. This method is probably 
the easier one for the untrained mixer, but unfortunately re- 
moves a great deal of the “punch” from the big crescendos. The 
second method requires some knowledge on the part of the mixer 
of the music that is to be played. When a crescendo is com- 
mencing, the mixer should start reducing the volume slowly 
before the loudness has approached the danger point, and having 
lowered it the requisite amount, leave it alone entirely for the 
remainder of the crescendo. In a similar manner the raising of 
the level for the very soft parts should also anticipate the 
actual pianissimo passage. 


New Exposure Meter 

( Continued from Page 31) 

between the two extremes, whatever the operator desires for 
the subject at hand. Accurate exposure readings are given 
for any type of subject, outdoor or indoor, and under any 
possible photographic light, natural or artificial. The B. & 
H. Photometer thus leaves nothing to guesswork and admits no 
chance of erroneous judgment. A simple initial adjustment cor- 
rects the instrument to the operator’s own vision and to the 
strength of a small flashlight battery which supplies current to 
the bulb’s filament.” 

Exposure readings are combined in the one instrument for 
either the Filmo 70 or the Filmo 75 cameras, and will later be 
made available for use with all types of movie still cameras. 
A full range of exposure readings are provided from F 1 to 
F 32. 

The following from the Bell Howell Company’s instruc- 
tions as to how to operate the Photometer will furnish a vivid 
glimpse of the instrument at work. 

“The Photometer is highly selective. It is often advisable 
to take two readings, one on the darker areas of the subject 
and one on the lighter part of the subject. Thus one can ex- 
pose accurately for the shadows and dark objects, or for the 
highlights, sunlit areas, and light colored objects — whichever 
will give the desired effect. Or one can select an exposure 
which will strike a happy medium between the two. 

“If the dark and light areas are about equal, use a stop mid- 
way between the two extreme readings. If dark areas predomi- 
nate, favor them in selecting the intermediate stop; if light 
areas predominate, favor them. 

“In taking close-ups of people, you will usually want to 
expose for the face and disregard the exposure requirements of 
the surroundings. The Photometer not only affords accurate 
exposure readings for a camera operated at the normal speed of 
1 6 exposures per second, but also gives the correct stop setting 
for Filmo camera speeds slower or faster than normal — 8, 12, 
24, 32, 48, and 64 frames per second.” 

The B. & H. Photometer weighs only 514 ounces. It is 
434 inches long and 1*4 inches in diameter. 


India Film Imports Increase 

A BIG increase in film stock imported into India is re- 
ported for the official year 1928-29. The total im- 
ports of film amounted to 30,000,000 feet, valued at 
28 lakhs of rupees, or about 210,000 pounds as compared 
with 23,000,000 feet, valued 26 lakhs in 1927-28. The in- 
crease was almost entirely in stock, most of which came from 
Germany and England. The raw film imports increased from 
12,000,000 feet to 19,000,000 feet, valued at 9 lakhs, or 67,- 
500 pounds. Imports from America and England of exposed 
film amounted to 13 lakhs and 2*4 lakhs in the previous 
year. Tariff on positive imports amounts to 4*4 annas per feet 
and the duty stands at 1 5 per cent. No increase is expected 
this year.

gested for the width of Wide Film, 
only one size has been developed to the point 
of production, this being the 70 MM GRAN- 
DEUR. Other sizes that have been experi- 
mented with have adopted the same ratio of 
size of picture but have included objection- 
able features that have precluded their use. 


70 MM GRANDEUR pictures are now being 
shown and others are in production. MITCH- 
ELL-GRANDEUR 70 MM CAMERAS 
were selected by the producers of these pic-

produce high grade pictures without costly

We are in production of 70 MM Cameras 
but will build any other size on special order 
if desired. This, of course, would cause delay
