Msdg6, I am sure you are finding trays easier than a tank, but I find opposite to be the case for me—we are all different, and you may have more experience of tray processing than I have. I find that I am faster, more precise, and end up with no scratched negatives by using a tank, CombiPlan in my case, with vigorous inversion agitation. I tested for uniformity of development, and using my densitometer I could not find a deviation larger than 0.03 logD, across the surface, on 6 sheets, exposed to different uniform tones. Had I had a Jobo with an Expert tank, I would be doing it even faster, and perhaps with even less concern for issues that smaller tanks can present. On the other hand, I enjoy trays when I only have a few sheets, especially from tests or other experiments.

By rotating two tanks, I will be able to do them all, I am sure, much faster than with trays, so I do not feel that I am creating more work for myself, although I appreciate that the opposite would be the case for you.
