and WHERE are you getting un-evenness? Edges, all over, random? I found that when I first started tray processing 8x10 film that when I process TOO LITTLE amount of film, I would have a higher tendency to have edge build-up of density(hot edges). Now, I do 6 sheets/run, and I no longer have problems. Personally, it takes me about 30sec to rotate through the stack, and then I let the film rest in the tray for the remaining 30s(1min total).
I'm using Efke 100 btw, but have considered switching to FP4+, hence my interest in this thread.
You mention "logs". I've never measured the density of my negs, but I've determined my developing time for my film and developer dilution(I use 2:2:100) for
"normal" by looking at my prints(lodima in amidol). So I can't comment on that part.
agitation:
I lift up the stack on one edge, and feel the bottom sheet out slightly, bowing it down. I then "flick" the sheet, forcing developer to run over it, and between it and the sheet above it, thus causing it to slide out easily. I've ruined a few sheets at the beginning when I first started tray processing, but now that I have a method, it works for me. I take the sheet out from the bottom of the stack, and holding it on both sides(with both hands), lay it gently down on the top of the stack, then pat it down on all for corners. Then proceed to do the same for the rest of the stack until fully cycled. Then I let the film "rest" for the remaining 30s until the next agitation cycle.
