Hello, I am just starting to experiment with a fridge full of old paper that was "given" to me for $20.00. Lots of old Ilfochrome paper, lots of old black and white, some of it expired in the '40s, most expired in '50s-'70s. A lot of the paper prints fine in the black and such, but, as expected, is fogged in the highlights. The tonality is great, but I am looking to clear the fog a bit. I have used Kodak Anti-Fog tablets several times on old film, and it helped. I know they don't have these any more, but they used to have several versions; some for film, some for paper, etc. I have read on this forum that both benzotriazole and potassium bromide can have anti-fog effects, but work in different ways, and cause cool and warm tones, respectively. My question is: what happens when you mix them? To try this, how much should I use? My developer is Ilford MG, and I usually use two liters at a time. Will anti-fogging agents work in a diluted A+B litho developer, or will the long developing times pretty much make them useless? Thank you in advance.
