So I tried it out today, and I broke the rules on two accounts...
1. I used a rapid fixer, Ilford Hypam. Said not to.
2. I did not print a photograph of high contrast to try on.
It still worked OK, it was hard to get an even result. And boy is this stuff stinky!
How important is it to use a standard (not rapid) non-hardening fixer?
The cupric sulfate bleach is cool. I tried it with some other toners and there's a lot to be had by experimenting with it, I can tell... Off to read up on the subject.
