Abstract: Photographic apparatus for locating a film cassette in position for the sequential exposure of a plurality of film units contained within the film cassette. The apparatus includes a film counter for indicating the number of unexposed film units remaining within a film cassette, and a film cassette counter which is indexed each time a film cassette is inserted into the apparatus or, alternatively, removed therefrom. When such a camera is returned to a repair facility, the reading of the film cassette counter may be used in connection with reliability studies, warranties, market research on film use, e.g., how much film is exposed in a certain camera model, etc.
