Abstract
A method of processing photographic material comprises developing the photographic material by treatment with a developer (26), and fixing the developed photographic material by treatment with a fixer (32, 38) while reducing the level of silver ions in the fixer (38) by electrolysis. Between the developing and the fixing, the photographic material is treated with an intermediate treatment liquid (44) for a period of time less than the treatment time with the fixer (32, 38). The intermediate treatment liquid (44) contains used fixer (38). The efficiency of fixing is improved without the use of substantially greater liquid volumes and in particular without the use of further quantities of water.
