Primeiro vídeo na pesquisa. Li, reli, reconheci. Bacana encontrar teu material, caro Wagner, sempre de excelente qualidade, e aqui muito chic em inglês! Eu não tinha em mente como pode-se usar essas técnicas enquanto técnicas artísticas, além de corretivas! Greetings from Rio!

Nice. I just bought some of my own to lighten the highlights on my prints.

this is very helpfull thanks! Any idea where to get the Potassium ferricyanide?

[@apenasimagens]

That changes a lot from country to country. Overall, procurement of raw chemicals is getting difficult for hobbyists all over the world. I know and use the following suppliers when I can't find a local alternative: stores.photoformulary.com/ or www.disactis.com/ or silverprint.co.uk/ and yet www.bostick-sullivan.com/

@@apenasimagens ok cheers.. I tried regular toilet bleach before but it either did not react or reacted too agressive. One more thing if you don't mind: This procedure is possible on earlier made, already fixed/dried prints right?

[@apenasimagens]

@@Hassebas88 Yes, it is possible also in fixed/dried prints. You just have to fix/wash them again.

@@apenasimagens thanks again! found a shop that sells the stuff in my country as well.. ordered it so I can get some moons to shine nice and bright.

You Can mention that if you go too far with the Ferro cyanide you can go back by redeveloping your print.
