A film cassette carries a plurality of film units of a type in which each unit includes a self-contained pod of processing fluid. After exposure of a given film unit, that unit is moved from an exposure position, past a spreader bar to spread processing fluid over the exposed area of the film unit and to a viewing position in which the processed film unit is presented in a camera window through which it may be examined by light passing through the camera window and the film unit.
