A photographic system for sound motion pictures, comprising a film cassette containing a strip of film, a supply of processing composition, and a processor programmed to apply the processing composition to the film upon manipulation of the film in the cassette and a film drive and projection system adapted to receive the cassette, and containing recording means to enable the recording of a sound track on the strip of film and the subsequent replaying of such recording. The recording means includes novel shielding means which extends at least partially over the cassette to ameliorate electromagnetic and electrostatic interference.
