An instant camera for exposing self-processing photographic film sheets (200) provided in a loose stack within the camera. The camera includes a mechanism for manually extracting each film sheet after exposure. The film extracting mechanism comprises a pair of opposed pressure rollers (310, 320), one of which has a gear pinion (130) meshing with the teeth (152) of a manually operable gear rack (110), and a pick or film gripper (144) provided at one end of the rack. Upon pulling out the rack from the camera body, the pick engages the trailing end of the uppermost film sheet such that the film leading end is moved into the nip between the opposed pressure rollers, which crush a bag, pod containing a film processing liquid developer and spread the liquid on the exposed film sheet surface while the film is being extracted from the camera due to continuated movement of the rack engaging the roller gear. An exposure counter disk (246) is arranged to be engaged by the rack pick and incremented during extraction of the rack. The camera can be a preloaded, single-use camera. The gear rack can be replaced by a continuous belt to be manually actuated by a slidable knob.
