Abstract
A photographic film assemblage including a film cassette having a hollow spool or core upon which a strip of film is wound. An end portion of the film is releasably secured to the spool by a release member mounted within the spool. The release member is adapted to prevent the end portion of the film from being detached from the spool during exposure of the film in a camera and to release its hold upon the end portion of the film upon the film assemblage being placed within a film processor, whereby the strip of film may be completely unwound from the spool during processing of the film.
