Are there any unique problems with doing 4x5 negs in open trays?
...
I've lately taken to doing 4x5 sheet film in one of these: http://www.summitek.com/cradle.html I get very even development. I've used the CombiPlan tank as dip and dunk, without the lid, with excellent results as well.
The Photographer's formulary also sells an item very similar to the Summitek cradle. You need 11x14 trays with the 4x5 cradles.

Can't help you with film choice's but beware of the inevitable scratches and fingerprints. Fill the trays with as much liquid as you can. Use 8X10 trays for 4x5 or 5x7 film. I used 5X7 trays for 4X5 and regret it---I do not use hardener in the fix's.

Bruce, this just goes to show you how everyone is different.
Before I developed in trays the first time, I read everything I could, but NO ONE told me that film, once immersed in developer, takes on the surface viscosity of eels. I put my little stack of film in an 8x10 tray and they went every direction they could. I bought a Jobo soon after.
Also, NEVER EVER EVER develop film without hardener in the fix. In my case, I might as well scratch them with a nail before loading the film holders.
If you must develop in trays, and you are hopeless with the manual techniques others have described, and you can't afford a second hand Jobo, get a slosher.

i guess i am lucky
i have been processing film in open trays for about 10 ( or 13?) years
never had problems. maybe 1 with scratches in all that time.
i process 4x5 in 5x7 trays, once in a blue moon in 8x10 ...
i never process less than 8 sheets, and have shuffled upto 28 sheets at once.
i guess it takes practice and luck ...

Hi John,
just curious what developer you use? I use PMK pyro and I think that with pyro and pyrocat developers, using the 8x10 trays with 4x5 film becomes much more important. I think that pyro developers have more problems with uneven development due to turbulence in the tray than conventional developers do.

Dan, just to provide a slightly different approach: I use PMK in the food storage containers you can buy in a super market, I think something like 6x8". I got the idea from Ken Lee's website, the section on processing. The containers are deeper than 8x10 trays (at least for me, more depth = less chance for scratches) and the reduced surface area (48 sq in vs. 80 sq in) means less PMK oxidation during processing. Rotating the negatives periodically, as I mentioned in my earlier post, seems to eliminate uneven development, since any turbulence is evenly distributed.Hi John,
