ABSTRACT:
The improved camera has a film chamber separable and disposable from the exposure chamber of a camera, with a self contained means for processing material for a diffusion transfer-reversal photographic system, with the material comprising a film negative, a glass plate in a mount, a liquid with activating chemicals in either a pod or incorporated in the negative, and a positive emulsion, either coated on the glass or on a film attached to the glass adhesively during processing. When processed, a slide in a mount results in a minute or so.
The improved camera, over my U.S. Pat. No. 3,045,572 of July 14, 1962 provides a larger image size within the constraints of proper interoccular spacing and lenses of a normal angle of view. The improved camera provides for a unique system of focusing, which automatically corrects the interoccular spacing of the stereo pairs when the distance is set.
Provided is a unique shutter for controlling exposures in a stereoscopic camera. A new method of attaching a camera magnetically to a tripod is provided. The use of two separated buttons to prevent accidental exposures without a lock is provided. Improvements are made in a viewfinder, to give a more clearly defined, illuminated frame, which also gives exposure information, and parallex correction is coupled to the focus system, in a new way.
