PCT No. PCT/EP90/00726 Sec. 371 Date Apr. 7, 1992 Sec. 102(e) Date Apr. 7, 1992 PCT Filed Apr. 24, 1990 PCT Pub. No. WO90/13061 PCT Pub. Date Nov. 1, 1990.A method of forming a dye image in a photographic silver halide element containing a dye-providing compound and having in a layer thereof an imagewise distribution of catalytic silver which comprises the step of treating the material with a redox amplifying solution comprising a reducing agent and a redox amplification oxidant characterized in that the redox amplification oxidant is removed from the solution after use and the so-treated solution is re-used after the addition of fresh redox amplification oxidant.
