From the two symptoms you describe; developer turning dark brown and being weak in its action, I would suspect you may have forgotten to add the sodium sulfite when mixing it. It's useful to keep a notebook and enter information on each ingredient as they are weighed out and added. For example, tare x grams chem y grams ------ totl z grams That way you can double check your work and also identify an error later. -----Original Message----- From: pure-silver-bounce@xxxxxxxxxxxxx [mailto:pure-silver-bounce@xxxxxxxxxxxxx] On Behalf Of Philippe Gauthier Sent: Wednesday, November 02, 2005 9:21 AM To: pure-silver@xxxxxxxxxxxxx Subject: [pure-silver] Ansco 120 failure 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)? The recipe here: Water (125 deg.
