Abstract
Abstract A motion picture system and method including a unique compact multipurpose film handling cassette-projector arrangement. The cassette is initially furnished with unexposed film and includes an arrangement for exposing, processing, drying and projecting that film in cooperation with externally mounted features of a camera and projector. After the film has been exposed with the cassette mounted in the camera, it is mounted in the projector which has cooperating features for effecting the processing, drying and projection of the film strip.
