Abstract
When using unstable processing solutions, high recirculation and/or replenishment rates may be required. However, this may result in non-uniform processing of photographic material in processing apparatus using such solutions. Described herein is apparatus in which agitation members (17) are provided in the processing tank. The members (17) are fixed to a wall (11) of the tank at a location (18). The member (17) has a free end (25) which is positioned to lie against emulsion surface (26) of material (20) being processed (or against inner wall surface (19) if no material (20) is present). As material (20) is moved along path (13).
