Commentaires sur la formule

Developed by Patrick Gainer.
Working solution: Dilute the stock solution 1+50 (20 ml per litre) with water before use. Developing times for 400-speed B&W films are around 9 min at 22C.
Notes: The working solutions of both PC-TEA and PC-Glycol are dilute in terms of developing agents (comparable to Xtol 1+3), but have relatively high alkalinity. In general, I find that PC-TEA gives finer grain than PC-Glycol. This may be due to a combination of gentler action (PC-TEA is much less alkaline than PC-Glycol with carbonate) and the mild silver solvent effect of triethanolamine.
