Has anyone had any experience with FSA toning of prints or negatives?\nAccording to Dr. Rudman, "When FSA toner redevelops the halides that\nhave been regenerated in the bleaching stage, it does so to a\ndifferent form, producing so-coalled 'colloidal' silver, consisteing\nof very small particles of different sizes and shapes." [The\nPhotographer's Toning Book, p94] Dr. Rudman only talks about FSA\nprint toning in his book, but I'm more interested in negative toning.\nIn particular, I'm interested in what the toning would due to fairly\ncourse grained film. Namely, will it make the grain smaller? Will it\ngive an interesting look? Does anyone have any experience with this?
