ABSTRACT:
A photographic reproportioning apparatus for changing one dimension of a two dimension image contact print exposed on a photosensitive film moved by a support plate in a predetermined linear direction with respect to the image being reproduced by a reversible synchronous motor. A stationary overlying film carriage supports the original image in contact with the photosensitive film. An opaque mask overlies the film support members and includes an aperture bar assembly moved by synchronous motors in the linear direction of movement of the sensitive film. The aperture bar assembly, interposed in the mask transversely of the direction of its movement, exposes the film from an overhead light source during movement of the mask.
