thanks Paul. that's sort of what started all this. i tried the tank using TD-201 from the Anchell/Troop formula. it seemed to work and not leave over-development marks. however i didn't have enough solution made up for this large tank, so i haven't been able to do a definitive test. divided developer leaves my negs looking a little flat...i may need to mix up a double dose and give it some proper testing. i needed reminding that i might be getting too far off course here, with this developer experiment.
