ABSTRACT:
A photographic camera is intended for use with a film cassette having a film-exposure status indicator movable from an unexposed position for providing a visible indication that a filmstrip within the cassette is generally unexposed, to a partly exposed position for providing a visible indication that the filmstrip is only partly exposed, and to an exposed position for providing a visible indication that exposure of the filmstrip is complete. The camera is capable of returning the filmstrip to the cassette prematurely when the filmstrip is only partly exposed and of advancing the filmstrip from the cassette subsequently to complete its exposure, and includes control means that operates drive means to move the status indicator from its unexposed position to its partly exposed position in the event the filmstrip returned to the cassette is partly exposed and to move the status indicator from either its unexposed or partly exposed position to its exposed position in the event the filmstrip returned to the cassette is substantially exposed.
