ABSTRACT:
A copy camera, preferably configured to make enlarged prints from 35mm slides, operates in at least two different magnification modes for providing either a full frame or cropped reproduction of the slide on a film unit having an image area format that differs from that of the slide. Magnification change is accomplished by locating the slide and film unit at alternative corresponding object and film planes that are located at different predetermined image and object distances from a projection lens. An electromechanical logic system provides an indication to the operator of which magnification mode has been selected and automatically inhibits initiation of an exposure cycle if the slide and film unit are not in the corrected corresponding positions to provide a focused image of the slide on the film unit.
