ABSTRACT:
A film drive mechanism for positioning film relative to an aperture in a riser block of a photographic printer. The mechanism provides the usual ability to adjust each frame of film in the X axis paralleling the direction of film movement, adjust each frame in the Y axis transverse to the direction of film movement, crop each frame by selectively varying the size and configuration of the riser block aperture, and selectively move each frame between portrait and landscape formats. Additionally, a mechanism is provided to rotate each frame of film relative to the aperture in the riser block so as to correct for exposures made with cameras that are not level.
