I was able to try my hand at some Sepia toning this past week with Azo & Kodak Sepia II Warm. I learned a lot, but ran out of prints to tone before I got it down. The first few I bleached out all the way, which only took 1 1/2 minutes. When toned, they were an ugly yellowy brown, which I don't care for. As I shortened the bleaching times, the color of the toned prints became more to my liking. I decided that, for the print I was toning, that about 20 seconds in the bleach was enough. I suppose, with the short bleaching, I was getting a split toning effect? One thing that surprised me is how Azo G2 & G3 produce quite different colors in this toner. The G3 was a little to yellow for my taste, but still acceptable. The G2 was a nice warm brown, which I really liked. I will try a thiourea toner for the next batch. And also a much slower bleach.
