Interesting thanks for the input Ian. I think part of my nervousness with stuff like this has to do with the whole bleach-redevelop thing, which I've not explored in any detail, nor ever tried, other than with paper just to play around with some toners. But since I don't tone my prints in anything other than selenium, I never went any further, and on the film side I've never needed that kind of process, so I'd really have to do alot of reading on this subject before trying it.
