lith bleach formulas and some experiments
I was doing some experiments over the weekend to dry to reduce the warm tone in some lith prints. I bleached them back in CuSO4/sulfuric acid bleach and found that when I redeveloped in lith, it came up nearly immediately and the tones were much closer to neutral.....like a warmtone conventional print. That made me think about the effect of the rehalogenating agent in the bleach. Most call for Potassium bromide, but can NaCl also be used as a direct substitute? I'd think the resulting redeveloped prints would be a bit warmer than they might otherwise. I'll give it a try in a few days if no one speaks up.
