An ecologically advantageous method for fixing a developed photographic silver halide emulsion layer material which involves the steps of: (A) developing an image-wise exposed silver halide emulsion layer with a developing agent in the presence of an aqueous alkaline liquid, (B) bringing the developed photographic material while still wet with the liquid of step (A) with its silver halide emulsion layer side in intimate contact with a water-absorbing layer of a receptor element, which layer comprises an organic hydrophilic colloid binder, a silver halide complexing agent, and in dispersed form a metal sulphide as silver ion scavenging agent, (C) maintaining said photographic material and receptor element in contact to allow the transfer of dissolved complexed silver compound into said receptor element, and (D) separating the photographic material from the receptor element, and wherein said water-absorbing layer contains said metal sulphide in colloidal form with an average grain size below 0.1 mu m, and in an amount at a sulphide ion coverage per m2 at least stoichiometrically equivalent with the silver ion coverage per m2 in the photographic material in its unexposed and undeveloped state, the molar coverage per m2 of said complexing agent being not lower than 1/20 of the molar coverage per m2 of silver halide in the undeveloped photographic material.
