Well, I've now done three batches of development of 4x5 sheet film in a Combi tank with 2-bath DiXactol, and here are the results. Despite the instructions indicating that dilution, not time, was the key factor, I found that 5 minutes for batch 1 gave very thin negatives. In addition, the suggested agitation of an initial 30s, followed by an inversion every 30s, gave very uneven stain, to the extent that these negatives are probably unusable. (The film was Fuji Neopan Commercial in Quickload format). For the second and third batches, I gave an additional 45 seconds for each bath, and adjusted the agitation to an initial one minute, followed by an inversion every 15s thereafter (i.e. PMK agitation). This has resolved many of the problems, but there is still some unevenness, especially in sky areas, which I have never experienced with PMK. The acutance seems comparable to PMK, and the stain is more subtle. Any further suggestions on how to obtain even negatives?(posted 8661 days ago)The next tests will probably be with TMax100, which didn't seem to do too well with PMK. However, Ilford Delta 100 / PMK Pyro seems at this point to be the most attractive combination. Any other thoughts on this?
