I don't use PC-TEA in my practice. Gainer does not specify target pH for this developer. Sandy King measured the pH of PC-TEA, and triethanolamine is a wrong buffering agent for that pH. N-methyldiethanolamine or N,N'-dimethylethanolamine would be a better choice depending on the target pH intended by the formulator.Originally Posted by fhovie
DS-1 is a good developer similar to D-76d. Differences: (1) DS-1 produces fine grain image like D-76d, but without mushy grains. (2) DS-1 is less reliable when kept, in light of XTOL failures and lack of any active means of preventing the problems in DS-1. The latter can be fixed, so I could issue a new version of DS-1, but I decided not to pursue that direction because DS-10 produces superior image quality with almost all films except APX100. (and I think Martin Jangowski found a couple more films that don't work well in DS-10.)
DS-1 can also be comapred to XTOL. Differences: (1) XTOL provides slightly finer grain. (2) XTOL provides slightly higher true speed.
After all, DS-1 is a good general purpose developer if you don't mind mixing from scratch, but otherwise, there's not much worthy of comments. (Therefore I don't mention it very often.)
