I know b/w developing is contingent on the shooting/printing style of the photographer, but... Is there a manufacturer spec for 18% grey in terms of statusM density? Like a LAD for color? For example, if I develop PlusX (exposed normal) in D76 straight, 18% grey should yield a density of 1.20 or something? B/w is not like color as there are many variables, but the manufacture must come up with suggested times of development of various stocks using some sort of aim middle grey.(posted 8638 days ago)Any ideas?
