Re: Developing sheet film in open-ended PVC tubes
I would have thought development of palladium prints in tubes would result in streaking as I've always read and been told that the developer should be 'dumped' on the print very quickly or 'tide' lines would result, especially with hot developer like P.O.

Development and clearing is done in tubes. I wash the prints in a traditional washer. What I like about it is that since I work with different Potassium Oxalate developers as my contrast control (a la Dick Arentz) I just have a bunch of developer bottles handy and don't have to mess with trays. That is, I develop a print and say its too flat, I just pop another in a tube with more contrasty developer.
Even if one doesn't use different developers, tubes are great. I can print up to 20x24 in the space that only 1 tray would take!! And when the print is in the tube spinning I can walk away from it and work on other things, like you say. Instead of rocking trays I rock myself to the music!
I'm curious about the use of the Jobo with PT/PD. Do you do the developement this way also, or develop first in tray and then do the clearing this way? Wash?
I've been thinking about a tube method at least for clearing so I can walk away and let it spin instead of standing there and rocking the trays to the beat of my favorite music.
Thanks,
Mark Nelson

BTW, I do all my film work (and print work with Pt/Pd) in Jobo drums.
While I have a Jobo machine one can use (most of) their drums on a
plain old Beseler rolling agitator. I don't see the advantage of open
tubes in trays (in the dark) if one can easily use tubes in the light
unless there's something I'm missing.
