(Not that I'd do that. Inverting is easier). Could, maybe, but it would be a major waste of chemicals. If you're gong to do it like a Jobo, lay it on its side, on a towel or something, and roll it back and forth at the rate a Jobo does it. You'll get the development characteristics of a Jobo, which is very even - John Sexton does all his film in a Jobo - and save a lot on chemistry, since it only had to be submerged at the bottom. More air in the tank also contributes to even development (as long as it's not air bells and there's enough chemistry to have the energy to do the film right). You could also do it with a Beseler motor base (used for doing color prints) that's not terribly expensive. Lots of options. But there's an advantage to not doing it continuously, if you're using compensating developer. But for the most part, continuous like a Jobo works great - horizontally. - -- Eric Welch St. Joseph, MO http://www.ponyexpress.net/~ewelch A modernfleet of ships does not so much make use of the sea as expoit a highway. - Joseph Conrad
