Abstract
A photographic film assemblage of the self-developing type is specially configured for use in conventional cameras including those of the 35mm type. Photographic processing apparatus is provided for use in conjunction with the self-developing type film assemblages which have been previously exposed by the conventional type camera. The film assemblages comprise a substantially lighttight cartridge into which the film strip may be rewound subsequent to exposure in the conventional type camera thereby facilitating its removal from the camera and its insertion into the processing apparatus which operates again to withdraw the film strip from its cartridge so as to effect the processing of the film strip. After processing, the film strip is advanced from the processing apparatus to provide a plurality of fully developed transparencies which may be cut and framed in a conventional manner.
