I have about 10 rolls of film that I've shot at the rated speed. What will happen if I try to process in Diafine? Will I be okay, or are they going to overexpose?
Thanks,
Jonathon

What film is it?

Without knowing what film it is, I would guess that the results won't be too bad 'cause diafine has a way of compensating so that the highlights don't get too dense. Depending on the contrast of the scenes you were shooting, you may get very very nice shadow detail this way, while still retaining some highlight detail.
Good luck. Please let us know what film and what happens if you do go for Diafine.

It's mostly Tri-X, which I know is particularly sensitive to the 'diafine push.' Also, three rolls of FP4+, and some HP5.
I have great luck with TriX at 1250 in Diafine. I think TriX in Diafine allows for a lot of latitude, but I would be interested to see how it comes out. Try one roll first and proceed with the others if the results are good.
The Ilford films do not push as far in Diafine as TriX. You may have better luck with those, though I have not used them in this combination a lot myself.
I think for all my choice would be to use a different developer, but I think Diafine can work for you.

Okay, so we're looking at two stops overexposure of Tri-X if developed in Diafine. I predict that all will be well...
The HP5 should definately be fine as it's more like ASA 640 in Diafine. FP4+ would be overexposed by 1 stop - no probs there!
Let us know if you try it!

I shot a roll of Tri-X rated at 400 in a Minolta Hi-Matic 7s-II that, at some indeterminate point during the roll, started defaulting to f16 for every shot. So some of the shots were metered correctly and others were underexposed by at least a few stops. Because of this, I processed in Diafine and the negatives were all usable. Here's a link to some of the photos.
You can definitely process Tri-X exposed at 400 in Diafine at get usable results; however, I wouldn't recommend it for development unless you've exposed it at ASA 1000 or higher and are taking advantage of the push Diafine gives. The grain of Tri-X done in Diafine is not particularly nice, you'd be much better off processing in HC-110 or something else.
