Abstract
Apparatus, e.g., a camera back, for locating a film cassette containing a plurality of individual, pre-mounted transparency film frames of the self-developing type in position for exposure. The apparatus includes a lighttight chamber into which the film frames are moved subsequent to their exposure. After the exposure of one or more of the film frames, the apparatus may be coupled to a film processor wherein the exposed film frames are individually removed from the lighttight chamber, processed, and delivered to the operator. The apparatus also includes a film advancing member which automatically removes a dark slide from the film cassette as it is being loaded into the apparatus.
