Abstract: Source, size, lens aperture, steadiness, film resolution, and similar factors govern the present-day and anticipated future limits of 8-mm motion pictures as to dynamic resolution, illumination, and possible sound on film. In order to evaluate the subject to screen performance of motion picture systems, a test method was employed which indicated the total resolution of the camera, film, and projector. In order to record resolutions equivalent to those seen by eye, it was found necessary to add the images of several frames because of persistence of vision. The same conditions appear to apply to television.
