Pseudo format camera and special film cartridge

摘要

A photographic camera is adapted to receive a conventional film cartridge for taking exposures for use in producing normal prints and a special film cartridge for taking exposures for use in producing pseudo telephoto or pseudo panoramic prints made by enlarging a selected portion of a negative. The special cartridge is distinguishable physically or otherwise from a conventional cartridge to permit the special cartridge to be routed at the photofinisher to corresponding equipment for producing the pseudo format prints. The camera is capable of distinguishing between the special cartridge and a conventional one to prevent the camera from operating in a pseudo format mode (though permitting it to operate in a regular format mode) whenever a conventional cartridge is received in the camera.
