ABSTRACT:
In a bottom-loaded camera, a light seal is located between a loading chamber adapted to receive a film cassette and a window in the camera back for viewing film-related information on the loaded cassette. The light seal is movably connected to the camera back in light-sealing engagement therewith and shields film from the cassette against light entering the window. Manual operation of an exterior member, moves the light seal away from the chamber to provide space for loading the cassette in the chamber, and against the cassette to effect a lighttight connection between the camera back and the cassette.
