ABSTRACT:
A camera of the self-developing type closes the viewfinder during the advance of an exposed but unprocessed film unit across the viewfinder path. A blade coupled with the shutter closes the viewfinder path upon opening of the shutter. Subsequent passage of an exposed film unit across the viewfinder path, which delivers the film unit to processing elements which initiate fixing of the photographic image, releases the blade for return to the open position. The shutter cocking movement provides the motion for opening the viewfinder capping blade.
