Hello. I would like to hear about how you have dealt with increased density around the edges of sheet film, especially when processing more than one sheet at a time in trays. Is it possible to prevent this build up of density? I have found that when processing one sheet at a time and using a brush to agitate I get a lot less density build up around the edges. But if I have a lot of film to process then this takes a lot of time, even with running four or five sheets one after another in the same tray of developer(ABC pyro). I will settle into processing one at a time if that is the only way to get the most consistent and even development with 8x10, 11x14, and 12x20 film, but I know that a lot of really good photographers are able to process more than one at a time with excellent results. Any suggestions are appreciated.
