I was reading up on film development by PMK in The Film Developing Cookbook. On page 76, the authors state (as one of the reasons PMK is a good formula) that P MK contains no restrainer, which is good because "most restrainers, especially b enzotriazole, tend to impair sharpness." Does anyone know whether benzotriazole would compromise the sharpness of printing paper as well? The reason I ask is that benzotriazole (I believe this was marketed in some form for a long time by EK as "BB" solution) is the key variable in a well thought-of amidol print devel oper solution known as "Fein's Formula".... What do you think? -jeff buckels ( albuquerque)
