ABSTRACT A METHOD FOR PROCESSING A PHOTOGRAPHIC MATERIAL. An ecologically clean method for processing an imagewise exposed photographic silver halide emulsion material which method comprises the steps of : (A) developing an image-wise exposed silver halide emulsion layer by means of (a) diffusible developing agent(s) in the absence of such an amount of silver halide solvent that would reduce the coverage of developed silver metal (Ag/m2) by more than 20 %, using an aqueous alkaline liquid, (B) bringing the thus developed photographic material while being still wet with the liquid used in step (A) with its silver halide emulsion layer side in intimate contact with a water-absorbing layer of a receptor element that contains in an organic hydrophilic colloid binder a silver halide complexing agent, also called silver halide solvent, and in dispersed form silver metal nuclei, (C) maintaining said photographic material and receptor element in contact to allow the transfer of dissolved complexed silver compound into said receptor element until the undeveloped silver halide in the exposed silver halide emulsion layer is substantially completely removed and a silver metal precipitate on said nuclei is formed in the receptor element, and (D) separating the photographic material from the receptor element, said water-absorbing layer containing said silver metal nuclei at a coverage of at least 0.1 g/m2, and said silver complexing agent at a coverage per m2 corresponding with at least 5 mole % of the molar coverage per m2 of silver halide in the unexposed photographic material.
