I've been using a Jobo rotary tank to do sheet film, but am now interested in trying out techniques with non-continuous agitation. The problem is that I do only one or two sheets at a time and most daylight tanks require a lot of chemical. Using a liter or more of one-shot developer every time I develop one or two sheets of film is going to be too expensive for me. In the past I've been a big fan of TMax RS which is replenishable. I've also noticed that D-76 and HC110 are replenishable, so they may be optons as well. I like replenishable systems because I can use the same developing times throughout the life of the developer. So, is there a developer with the following characteristics? - Reusable - Replenishable - Economical - Development times that are long enough to work with slow filling daylight tanks. - Works with reduced agitaton techniques - Will still be available in some form after Kodak/Ilford get out of the business Comments and suggestions would be appreciated. BTW, I do not want to use trays because I just don't like spending that much time in the dark.
