ABSTRACT:
A photographic film assemblage including an elongate composite film structure of the self-developing or instant type for use in conventional still type cameras of the non-self-developing or non-instant type. The composite film structure includes first and second sheets which are coiled within a cylindrical cassette such that only the first sheet is uncoiled and photographically exposed within such camera. A rupturable container of processing liquid is carried by one of the sheets. After the first sheet has been exposed, it is recoiled into the cassette and the latter is then removed from the camera and placed in a processor. The processor removes the first and second sheets from the cassette in a sequence which eventually locates the second sheet in engagement with the first sheet such that the former functions to aid the spreading of the processing liquid between the two sheets as they move between a pair of rollers to initiate the formation of a visible image within the composite film structure.
