A process for forming a photographic image includes a colour development step and a bleach step, a redox amplification step separate from the colour development step, the amplification step and the bleach step take place in a single processing solution and wherein (i) the bleach amplifier solution contains hydrogen peroxide or a compound which releases hydrogen peroxide during processing and (ii) the bleach amplification step is effected by applying to the surface of the photographic paper or other material an amount of bleach amplifier solution in the range from 20 to 500 ml/sq metre, preferably 30 to 70 ml/sq metre, and wherein the solution applied to the surface is used once only. The invention also comprises an apparatus for use in the bleach amplification of photographic paper or other material comprising (i) a pair of generally parallel closely spaced apart sheets (ii) means for feeding the photographic paper between the sheets and (iii) means for feeding bleach amplifier solution to the space between the sheets. The gap between the sheets is preferably such that in use they are held together by the surface tension of the bleach amplifier solution. <IMAGE> |
