Friend of mine and I have a deal going where I do his black and white rolls free and he gets my colour rolls done for me for free... He just gave me today a roll of 100 speed Neopan SS. Presumably he'll never shoot it again because it's discontinued but us kid's don't have much money and hate to discard anything. I say this because having loooked around the net for a good half hour, I cannot find any developing times for Neopan shot at 100 ISO and developed in Tmax Dev. Presumably this is because it is deemed silly to pull the film (which is actually 200 ISO, just coded for 100 for some reason). There is a time for 400 and 200 ISO in tmax... is it possible to just determine some sort of linear relationship between the times and iso? or does anyone have any advice? Thanks, Will.
