Re: Developing sheet film in open-ended PVC tubes

yeah, I think it may have been that, too. I had thought View Camera,
but I remember getting Darkroom Techniques for years and they
probably were the source. It was a nice mag. Too bad its gone.

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.
