I mixed some Ansco 120 according to the recipe listed below yesterday,
but the experiment failed. The developer was weak and the development
was uneven, some parts of the picture never developing (usually the same
areas from one picture to another). I first tried with the standard 1:2
dilution, then added all my stock; it improved he stuff somewhat, but
not enough.
What went wrong? I'm pretty sure that the chemicals were fresh enough
(and except for the metol, little can go wrong anyway) but the mixture
turned a deep brown (not black as Ansco 130, though). Does this soup
need some kind of ripening? Was it possibly too warm? Contaminated tap
water (I usually use demineralized water)?
