Hi, I've been reading "The Photographer's Toning book" and would like to try chromogenic toning. But neither p-Diethylaminoaniline sulphate Sodium formaldehyde sulphoxylate Are on the chemical list of my usual supplier. Can I sub something for these two? Looking at the rest of the formula it gets worse. 4-Nitrobenzyl cyanide Acetoacet-2 5-dichloroanilide 2,4-dicloro-1-naphthol 1-naphthol Should I give up or are these things easily available?
