ABSTRACT:
The still camera in its preferred form is designed to accept the nornal 35-mm. film cartridge. The camera lens and aperture, however, are offset vertically above the normal positions for the lens and aperture such that as the film is advanced, only the upper half portion of the film is exposed. The horizontal length of the image frame can be the same as a normal 35-mm. exposure while the height or width as measured vertically of the frame is one half the normal 35-mm. image. The take-up reel is especially designed to cooperate with a magazine which is provided with a lightproof slot, the spool or reel being separable from the magazine manually so that a person can easily thread the leader of the film onto the spool and insert it in the lightproof magazine. The exterior dimensions of the magazine are substantially the same as those of the cartridge, the arrangement being such that when the film has been advanced in one direction to complete exposure of the upper half of the film, the cartridge, film and magazine may be removed as an assembly, inverted and replaced with the magazine now being received in the place formerly occupied by the cartridge and the cartridge being received in the place formerly occupied by the magazine. The film is then rewound on the cartridge automatically while exposing the lower half of the film so that twice as many pictures having the same given horizontal length can be taken with a single roll of 35-mm. film as has been possible with a conventional camera.
