I beg to disagree with this statement. CD4 is about $25 for 100g. There are about 5g/L of developer, so 100g makes almost 20 liters. Each liter should be good for at least 5 or 6 36 exp 35mm rolls, so 100g CD4 would be enough for close to 120 rolls. The only other relatively expensive chemical in C41 developer is hydroxylamine sulfate, of which 2g/L is used. I would guesstimate the developer only cost at closer to 50 cents a roll than $2 if mixing it yourself. Maybe you meant to say $45 for 100 rolls, not $100 for 45 rolls?
