Abstract
A photographic film unit, which includes a photosensitive sheet and a cover sheet separated by a spacer, is provided with a small access port for introducing a processing fluid from the exterior of the film unit into the space between the sheets and a small venting port for releasing air displaced from such space by the introduction of the processing fluid. The spacer surrounds substantially the entire edge perimeter of the film unit in a border area thereof. The access and venting ports extend through the spacer in this border area at diagonally opposite corners of the film unit.
