Abstract: An instant or self-developing transparency film assemblage for producing a 35 mm film transparency ready for mounting in a frame for subsequent viewing in cooperation with a viewer or projector. The film assemblage includes (1) a film chip having an opaque rear surface (2) a first opaque leader for initially covering a front or lens facing surface of the film chip to protect a photosensitive or image-recording layer of the film chip from exposure during the loading of the latter into a camera, (3) a second leader for enabling an operator to pull an exposed film chip between a pair of spread rollers which spread a processing liquid between layers of the film chip to initiate formation of a visible image therein, and (4) a sheet of opaque material which is adapted to be laid across the lens facing surface as the film chip is moved between the spread rollers.

Abstract: Apparatus having a first chamber, for receiving a film cassette containing a plurality of film units of the instant type, and a second chamber, into which the film units are adapted to be sequentially advanced subsequent to their photographic exposure. The second chamber includes a film counter mounted in lighttight relation therewith for indicating the number of exposed film units contained within the second chamber.
