ABSTRACT OF THE DISCLOSURE Photographic camera apparatus for processing exposed film units of the self-developing transparency type including two superposed resilient coiled opaque sheets adjacent the opening thru which exposed film units are advanced from the camera. The sheets are bonded in light tight relation along two opposed edges thereof such that an exposed film unit advancing from the photographic apparatus through the exit opening intervenes between the superposed sheets. The advancing film unit there- after operates to uncoil the coiled sheets so as to remain outside the photographic apparatus in light tight relation with respect to ambient light which might other- wise reach the film unit prior to the period required for its complete development. Once the film unit has been developed, the photographer may grasp the leading edge of the film unit and withdraw it from between the opaque sheets afterwhich the resilient sheets automatically assume their coiled state.
