[Alt-photo] Re: A DEFINITIVE ANSWER?

[Philippe Ayral]

I did try procedure for bleaching out black spots on pt/pd prints using
very dilute HCl and then
very dilute chlorine in a tray but never really succeed. If you want to try
you will have to do it outside, fumes are really dangerous and I am not
chemicals paranoic as lot of people are. HCL bleaching will bleach a little
highlights but not shadows.
Somebody has to find potassium ferricyanide equivalent for palladium prints
