Which tank would you prefer for 4x5

[Steven Ruttenberg]

The jobo 2520 or the 2550? The advantage I see of the 2550 is I could do an 8x10 sheet in it. These would be used for inversion processing. The advantage of the 2520 is it is smaller, but it still can do 6 sheets of 4x5.

Probably the only thing I'd be concerned about with 8x10 in the 2550 is fill time. If a pre-soak is used, then the extended fill time may not matter. Only testing will tell the tale.

I would also consider a more dilute developer solution like 1:62 for HC-110 or 1:9 for Tmax Developer, and so forth. That should also help. I guess fill time would need to be looked at once I get the tank (if I get the big one. But I am leaning that way. The smaller tank (maybe I get that as well) would be perfect for 4x5, especially or maybe especially for a stand/sem-stand process as well as standard process. The advantage of big one is when I have a lot of images from a trip to process and I will be using the same process for all of them.

No idea what kind of budget you're looking at, but you may want to consider this for 4x5:

I have one and it works very well with semi-stand or stand techniques; and, it holds 10 sheets of film! Additionally, for those of us that live "on the surface of the sun" (I'm just north of you) this tank is a dream for temperature control. Anyway, just thought I'd point out another option.

Thanks, I will check it out. LOL! Yep, and this coming year I suspect it will be closer to the center of the sun!

ps, when not processing film, I can mix drinks with it!

I have had great luck with the Combi Tank.

What is the minimum liquid amount required?

honestly, if you have the space (and funds) I would suggest dedicated tanks/drums. I have the jobo reels for 4x5 but prefer to use the Expert drum. 8x10 is either Expert drum or a Simma tube (very affordable and can also do 4x5)

No minimum. You need 1,050 ml to develop one sheet or 10.
