Abstract (en)

A method of processing a photographic material in which the wash water or stabiliser solution is treated with an absorbing agent in order substantially to reduce the amount of retained developing agent in the solution. The method is preferably a redox amplification process, especially one with no 'tailend'. The absorbing agent may be an ion exchange resin but is advantageously activated carbon.
