FSA (i.e. thiourea dioxide) Toning
Has anyone had any experience with FSA toning of prints or negatives?
According to Dr. Rudman, "When FSA toner redevelops the halides that have been regenerated in the bleaching stage, it does so to a different form, producing so-coalled 'colloidal' silver, consisteing of very small particles of different sizes and shapes." [The Photographer's Toning Book, p94] Dr. Rudman only talks about FSA print toning in his book, but I'm more interested in negative toning. In particular, I'm interested in what the toning would due to fairly course grained film. Namely, will it make the grain smaller? Will it give an interesting look? Does anyone have any experience with this?
