This picture as you can see was taken in a busy American city this picture was
taken at exactly the same time and at the same spot question.
How was it done among your motion picture camera photographed the traffic in action
while
but the care camera the great great granddaddy of all cameras was used to photograph
the buildings a little the action of this camera is so slow
that there isn't time for moving objects to register on the film on the other hand
the buildings being stationary gradually formed a sharp clear image
and why use the de guerre camera to show
that any picture of America without automobiles is hopelessly out of date.
