Summary:

HEREIN is described a time-stretching or slow-motion camera that makes exposures at a normal rate for this camera of 3200 per sec. When these are projected on the screen at the standard rate of 16 per sec., the action is 1/200 of the speed of the original movement of the subject.The film passes through the camera at the incredible speed of 200 ft. per sec., yet the pictures are asserted to have real photographic qualities, with halftone values like other motion pictures, and not to be "jumpy" when projected.These results are obtained by unique construction whereby the film is moved continuously by an electric motor while the exposures are made through a series of 48 matched lenses mounted in a rotary disc that passes them before a fixed shutter.Despite the speed of operation, the duration of exposure of each picture or frame is more than 25 times that possible with an intermittent-film camera.This new camera affords a means for the study of many problems in science and engineering, some of which are not possible of accurate solution in any other way. Various applications of the instrument are suggested by the author
