ABSTRACT:
A low volume developer tank system for the sequential processing of films that require different concentrations of bromide ions in the developer solution comprises a developer tank (2) provided with an ion exchange column (30) for removing bromide ions from solution which column can be engaged and disengaged and a plurality of reservoirs (6,8,10,12,14) arranged to feed individual replenisher components to the recirculation system (20). When processing a process C-41 compatible film the system is preferably operated with no bromide in the replenisher and removal of bromide from the developer is by overflow. When processing a film employing zero or very low bromide, the system is preferably operated with no bromide in the replenisher, substantially no overflow and removal of bromide from the developer is by ion exchange.
