ABSTRACT:
An improved film format for a self-developing, peel-apart film unit having flexible positive and negative sheet elements and a pod of developer liquid, wherein at least one of the sheet elements bends when a force is applied to a trailing edge thereof to effect sheet element movement. Pockets are formed on the leading end of each sheet element so that a force may be readily coupled thereto without bending either sheet element while they are being moved, for example, into a developer liquid spread system for subsequent film processing.
