I know ansco/PF 130 makes a good split developer for paper. I also know several folks here use ansco 130 (well... two or three) for film. Does anyone have any experience using ansco 130 as a split developer? I'm interested in a split developer that uses the same time regardless of temperature, and develops up to a certain point and stops regardless of how long the film's in the soup. Would ansco 130 fit the bill?
