I forgot to say that ascorbic acid and amidol are almost certainly synergistic. If so, the ascorbic acid will reduce the pH and INCREASE activity. What it does to image tone, etc, I won't try to guess. I have a feeling, though, that you would not be any better off than with ascorbic acid and metol, p-aminophenol or phenidone but would be spending more money.
What do you all use to sharpen those with- a Mobius strap?
A Mobius strap is the preferred method - but watch your fingers!
By the way, my amidol working developer sample was DEAD at 48 hours (base + fog only). It was still alive and working at 34 hours.
I took a look at the previously developed film (cross section) in an optical microscope. There appears to be a tanned "skin" at the top surface of the emulsion layer. The stain penetrates all the way to the bottom of the emulsion layer.
Recall that I uniformly exposed these pieces of film to a diffused halogen light source, so I would expect the development and stain to be uniform.
Wow, impressive! Just as an aside here Tom, the Moersch Catechol paper developer in working solution form lasts about 3 weeks or 8 separate printing session - fresh, the image comes out after 30 secs; on the 8th session or nearing 3 week old, it takes about 1 minute. I suspect they mix the stock solution with more than just water.
I can't wait for your tests on paper with MS Amidol liquid kit form.
