Update to my earlier note:
Have just reviewed notes I made at Phil Hoffman’s Film Farm this summer, where
Ricardo Leite gave an organic processing workshop, and wanted to share here.
Ricardo has developed recipes to replace bleach with hugely less toxic
alternatives for B&W reversal. See recipes and beautiful results here:
He skips a clearing bath, with good results. Images are more contrasty and
have a browner cast than if clearing bath is used.
Amanda: Ricardo has found that salt works as a fixer, but it takes about 3
days of soaking.
I also noted that Phil Hoffman doesn’t use fixer when processing B&W reversal,
tho’ he keeps it in for negative. He says it may fade in 10 years or more, but
so far his prints of less than 10 years don’t show fading.
