>>3706262>>3706259Although thats probably unnecessary (sulphite), its necessary if you want to go from bleach to colour developer, such as doing weird shit like developing C-41 in Rodinal 1:100 stand, fix, bleach the silver neg back to silver halide, then colour develop, bleach and fix, to get a colour image formed by Rodinal etc (dyes replace the negative developed by Rodinal in this instance).
Pic related are the ECN-2 steps with a ferricyanide bleach, which is similar to C-41.
