I have several fibre prints which are printed about half to one stop darker than I would like, can I use potassium ferricyanide as bleach to brighten them up a bit? What is the best dilution ratio? Is it still okay to selenium tone the prints after bleaching?
Asked by: Scott C.
It is better to use a Farmer reducer for a whole print bleaching. And yes after the bleaching prints can be toned in celenium.
