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. The opaque sheet, in combination with the opaque rear surface of the film chip, define a lighttight chamber to protect a developing image in the film chip as it is removed from a camera.

35 mm self-developing transparency film assemblage

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.
