Abstract of the Disclosure A doctoring surface conformation for applicator nozzle structures in photographic film cassette contained processors by which a coating of processing fluid may be deposited on a moving run of an exposed film strip. The doctoring surface conformation is defined as a planar surface spaced in parallel relation to the film strip which is urged toward a pair of guide tracks positioned on opposite sides of the planar surface. The sides or edges of the doctoring surface are delimited by vertical walls converging in the direction of film strip travel so as to develop a suitable hydrodynamic force in the processing fluid ?le minimizing the capture of minute foreign particles such as dust which may be carried on the surface of the film strip to be coated.
