ABSTRACT:
A photographic copying device capable of storing, exposing and processing both color and black and white photosensitive material including an exposing chamber which can be made light tight for handling color sensitive material or safelight protected for black and white material. Positioning stops in the exposing chamber make it possible to orient photosensitive material in complete darkness. The copying device can be operated in ambient light through light baffles. The material being photographed may be transparent, opaque or in the form of slides. A slide projector section directs light from the slides into the exposing chamber. A central control panel governs all copying operations.
