ABSTRACT:
Apparatus for processing photographic material has a plurality of stages for carrying out different processing steps. At least one stage has a series of processing regions each defined by an inclined surface that extends between sets of rollers. The surfaces may be of different length to provide different residence times for the material. Processing solution flows down the surfaces whilst the photographic material is driven upwards in counter-current mode. All the stages may be uni-directionally inclined end-to-end, or they may be arranged in a U-shape so as to minimize cross-contamination between the stages.
