ABSTRACT:
A system for developing photographic film which is ecologically friendly includes a tray holding a pair of film cassettes. One cassette includes negative film sheets which is inserted into a camera where the negative sheets are exposed. The exposed sheets are delivered to a developing apparatus. A second cassette from the tray includes positive film sheets and it is delivered to the same developing apparatus. The empty tray is mounted on the developing apparatus. Each positive film sheet includes a rupturable pod of developer liquid for spreading between mated positive and negative film sheets. Exposed negative sheets and positive sheets are mated and the pod ruptured to spread liquid between the two as the mated sheets move in a first path into an imbibition chamber. A pick at the exit end of the imbibition chamber strips the evacuated pod, negative film sheet and residual developer liquid from the positive sheet and delivers them to the face of a ram. The ram pushes the negative film sheet and other trash materials into the tray originally transporting the cassettes. Subsequently, the positive cassette is deposited within the same container which is then transported to a site for recycling and disposal.
