In the pamphlets accompanying Kodak's Flexicolor(C-41) chemistry, a clear discussion is provided regarding useful capacities (rolls of film that may be developed per quantity of developer). These discussions include variables such as frames/roll, different film speeds/types, and replentishment and also provide adjustments to development times as the developer is exhausted.(posted 9320 days ago)I've been unable to find any useful discussion of useful capacities for Kodak B&W developers. I use both HC-110 dilution B and TMAX developers and develop only 35mm film in 24 and 36 frame rolls in small (two-roll) tanks. What are the useful lives of these developers in terms of rolls of films without replentishment and of HC110 with replentishment? How about adjusted development times to account for developer exhaustion? The only Kodak doc I've seen regarding this speaks in terms of 8x10 sheets or equivalent. What is the equivalency in terms of roll film? Can anyone suggest a publication or source for answers or answer these questions from experience?
Thanks, Robert
