ABSTRACT:
A photographic film developing process and apparatus incorporating a processing chamber in which a resilient membrane forms one wall of the chamber. A photographically sensitized exposure is positioned within the chamber with its emulsion surface disposed in close juxtaposition to the membrane. The constituent components of photographic processing chemistry for the emulsion are sequentially introduced to the chamber and, simultaneously, the membrane is cyclically deformed to provide application and agitation of the processing chemistry.
