I just tried it for sheet film development. I tried what I had shot as test negatives:
1. Ilford Delta 100 4x5
2. Kodak TMax 400 4x5
3. Ilford FP4 5x7
4. Ilford HP5 5x7
The negs all look much better than I had hoped. If I have time tonight when I return home I will scan them to see if my first visual impression is right.
I diluted 1+4 and the full cycle was between 3 and 5 minutes. Next time I'll try 1+10 upon John Nanian's advice. Slow it down a bit, avoid uneven development.
