Developing 4x5 negs in trays.

Dan, just to provide a slightly different approach: I use PMK in the food storage containers you can buy in a super market, I think something like 6x8". I got the idea from Ken Lee's website, the section on processing. The containers are deeper than 8x10 trays (at least for me, more depth = less chance for scratches) and the reduced surface area (48 sq in vs. 80 sq in) means less PMK oxidation during processing. Rotating the negatives periodically, as I mentioned in my earlier post, seems to eliminate uneven development, since any turbulence is evenly distributed.

Hi Pete,
sounds interesting - to be honest, I develop most of my film in a Jobo. I have only used tray development a few times when I wanted to experiment with minimal agitation to see if I got more edge effects. In that case I processed 1 sheet at a time.
