Modifying developers for developing old film
I have a couple of old rolls of family film (10-40 yrs old) some color, some black and white. Today I was trying to develop a roll of kodacolor X in rodinal 1:50. I'm just trying to reduce some silver and not bothering with the dyes. I could see very very faint frame lines after fixing. So I believe something is there, on this particular film, but is fogged horifically. Could someone suggest time, temperature, or. chemical modifications I can use to develop this particular film, and perhaps the others, too. I have rodinal, D-76, sodium sulfite, lye, and benzotriazole at my disposal.
