Abstract: A compact and energy efficient apparatus for processing and drying an elongated strip of photographic film having a succession of film processing tanks containing selected processing liquids; drive system which advances the film strip endwise through the tanks to selected depths in liquids corresponding to required exposure times of the film to the different liquids while reducing the tank to tank contamination caused by the transport of treatment of liquids from tank to tank, and a heater system which reuses the waste heat generated by the mechanical and electrical components of the apparatus to dry the film strip as it emerges from the successive processing tanks.
