Hey everyone,
I thought I would post an update. I printed a batch of contact prints on AZO using Rodinal 1:10 in a tray and I am most impressed with the results. (not of the photos but the developer) One tray full (about 1000ml total soup) was still active long after I was ready to go to bed. Once the soup got sort of a funky brownish color with grains of silver floating in it, it seemed to work even better. An added bonus of the brownish color, I could turn on the overhead lights while it was at the bottom of the tray, and it wouldn't effect the print at all.
Prints came out, very sharp and very black blacks. When I get them flattened out I will offer a couple in the print exchange gallery if anyone is interested in seeing a first hand result.
