The Kodak site has data sheets on all their developers. The capacity of each developer is stated. It may be by the number of rolls per quart/liter/gallon. In that case just divide to figure out how much developer per roll is needed. If the numbers are given as so many rolls per volume, then so many more rolls at a longer time. Then you can either use the larger amount for the normal time, or a smaller amount for a longer time.(posted 8948 days ago)As far as I know, Xtol is the only one with serious limits on the quantity. As I recall, you should have 125 ml per 36 exposure roll of film of undiluted developer.
In a rotary processor, you may not be able to use high dilutions without using a larger tank, not full of film. I know that is true with the Jobo 1500 series of film tanks.
