Method of making images by image-wise exposing a silver halide emulsion layer, developing it with an alkaline processing solution in the presence of a silver halide solvent and causing silver complexes to diffuse from the emulsion layer into a non-light-sensitive image-receiving layer in the presence of development nuclei thereby to form a silver transfer image in that layer, said transfer image formation occurring in the presence of at least one 1-phenyl-substituted tetrazole copmpound, which influences the density and tone of said transfer image, said compound being contained in said image-receiving layer and/or in said processing solution and being a 1-phenyl-5-mercapto-tetrazole or a tautomeric thione form thereof carrying, on its 1-phenyl group, one or two substituents chosen from the group consisting of COOM or SO3M, (M being hydrogen, ammonium, an alkali metal atom, or an organic amine) and acylamido comprising a hydrocarbon group selected from the class consisting of a straight-chain or branched-chain C1-C8 alkyl group, an aryl group, and an alkenyl group, wherein said hydrocarbon group may carry COOM or -SO3M, M having one of the significances given above, and/or may be interrupted by at least one ether or thioether function. The invention also provides an image-receiving layer and/or a processing solution incorporating such density- and tone-controlling compound.
