I have ended up using developers that work well with the Jobo, and adjusting my methods of shooting accordingly. I am willing to do this because the other tanks I have used (HP Combi and Yankee) don't do nearly so good a job with sheet film. If I want Diafine-type results, I use Acufine instead, which works fine in this unit. But I have not been in many circumstances in which xtol or D-76 won't do the job. My methods are not sophisticated or complicated enough that agitation control rules out the use of the Jobo. Even night photos, which I used to develop using a semi-stand method, I now subject to a version of the zone system and get better results with constant agitation. But again, it is what I am willing to do, and I say it just to show that it is possible.
