Calling all 5x12 shooters, all 5 of you. I am looking for developing options - my darkroom isn't dark enough (nor really a room honestly) for me to be comfortable tray processing.

I understand my options are:
Trays
Jobo 3004 - very hard to find
Jobo 3005 - sticks out the end but works
BTZS tubes - 8x10 size maybe?
Send it out for processing.

I am currently processing all of my films in stainless steel tanks. I've used a Jobo before but don't own one.

Am I missing anything? I am looking for a cheap option for daylight processing - right now it looks like BTZS tubes, but am looking for any suggestions.

Jobo 2840 print drum. Use the 5x7 paper spots.

Check the threads on 5x7 film processing. IIRC Ole has a few posts explaining this.

The Jobo 2840 sounds ideal, and it looks like I can use it with a uniroller base. I would assume it will hold 2 sheets of 5x12?

I use the Jobo 3004/3005 option on a unicolor motor base.

Okay - I have acquired a Jobo CPP-2 and a 2840 drum. However, I don't see any clips or anything to separate the film in the drum. What's the trick here?

I'll put in another vote for the 3005 drum- even though the negs stick out at the end a tad, it has no negative (pardon the pun) impact on the processing of the film. I get full, even development of the entire piece of film. If I were to use the 2840, I think I'd do one sheet at a time, to make sure one didn't slide around during processing and overlap the other.

I would think you could also use one of the Beseler 11x14 drums, 2 sheets at a tmie. It's what I use for 2 7x11 sheets of film. They show up here and on the bay for a decent price.

NOTE: if using one of the Pryo developers you COULD end up with some 'banding' - bromide drag, area where the stain builds up a bit to much. some have issues with it others do not, never know when it will show up.

I've had no issues with banding or bromide drag since using Pyrocat HD. I know there are several other Pyro formulas out there that were designed for rotary processing - Rollo Pyro, the other flavors of Pyrocat (MC, etc), and possibly 510 Pyro. I know that the original formulation of PMK Pyro and ABC Pyro had banding/bromide drag/unevenness - PMK has been reformulated recently so I cannot say if it works any better in rotary processors or not.
