Abstract
A photographic film assemblage including a container, a plurality of self-developing film units within the container which are adapted to be sequentially exposed and treated with a liquid processing composition, and members associated with the container so as to form an integral part of the assemblage for controlling the distribution of the liquid processing composition during treatment of a film unit. A photographic apparatus with which the film assemblage is adapted to be used includes structure for locating the distribution control members in operative association with a film unit located in position for exposure and subsequent treatment with the liquid processing composition.
