Abstract (en)
A method of processing photographic silver halide material in which developing solution is treated to remove developer seasoning products and is replenished with a sufficiently small volume of replenisher components that substantially no overflow is produced characterised in that it includes a step in which a developing solution is treated with means to remove continuously substantially all bromide ion from the solution and to maintain the solution substantially free from bromide ion during operation of the method.
