Abstract: A cassette for a photographic film system adapted for processing after exposure by face-to-face contact of the negative with a positive processing film, the cassette having multi-part first and second chambers for containing the respective roll film elements at opposite ends of a central tray-like support. The negative film element, being light sensitive, may be packaged in a light-tight chamber defined by one of the two housings. The packaged negative element and cassette part defined thereby may be subsequently joined to a positive film chamber or loaded with a processing film element which, being insensitive to light, is preferably loaded under daylight conditions. After assembly of the film elements in the cassette, leading ends of both are connected so that in operation, film elements may be drawn simultaneously from their respective chambers for processing.
