FILM FLATTENING IN AERIAL CAMERAS

BASED ON THE PREMISE THAT FILM IS TO BE USED IN AN AERIAL CAMERA RATHER THAN EITHER GLASS OR A RESEAU, SEVERAL TESTS ARE CITED AND ANALYZED. THE FILM SURFACE HAS DEVIATIONS OF 6 TO 7 MICROMETERS IF IT IS VACUUM BACKED; THEY HAVE AN EXTENSIVE DISTRIBUTION OF 4 TO 5 MICROMETERS. THE DEVIATIONS OCCUR IRREGULARLY OVER THE AREA OF THE FILM AND ORDINARILY DO NOT CORRESPOND WITH THE HOLES IN THE CAMERA BACK. AN AMATURE CAMERA WITH MECHANICAL FLATTENING SHOWED EVEN LARGER DEVIATIONS.
