Apparatus for processing a transparency film assemblage subsequent to the photographic exposure of its instant type film frame. The apparatus includes a pair of rollers for spreading a layer of processing liquid between the film frame and a strip sheet, a stripping roller for grasping a free end of the strip sheet and removing it from covering relation with a visible image in the film frame, and structure for folding an apertured section of a film mount into face-to-face relation with another apertured section of the mount such that the film frame is sandwiched therebetween with its image area in alignment with the aperture in each section.
