A photographic film pack including a container having a forward wall and dependent end and sidewalls formed of a rigid vapor-impermeable material such as sheet metal and an opening at the rear; a plurality of self-developing film units each including a photosensitive element stacked within the container; a support member located behind the stack of film units; a battery located behind the backing member; and a vapor-impermeable closure for the opening at the rear, the closure being displaceable relative to the forward wall. The forward wall includes an exposure opening and one end wall is formed with a withdrawal opening for the film units. A vapor-impermeable cover is removably secured to the container in closing relationship to the exposure and withdrawal openings. The film pack is adapted to be employed in electrically operated photographic apparatus, having a spring-biased pressure member adapted to extend into the container through the opening at the rear for urging the film units toward the forward wall to locate the forwardmost film unit in position for exposure, and spring-biased electrical contacts for engaging the terminals of the battery to couple the battery to electrically energized means within the camera.
