Hi all, I've been working with a few different concepts that I want to print in alt processes. I'm considering using the Kallitype process but I have one question that needs answering. When using this process can I use a bleach (perhaps using Potassium Ferricyanide) highlights or reduce tones like I can in gelatin silver? What I mean is can the print be dunked in a bleaching solution to reduce it overall and/or can a bleach be applied locally to highlights to raise them? Following this bleaching, will I then be able to tone the prints as is typically recommended for Kallitypes?
