Tri-X Sheet Film Development : LUSENET : Large format photography : One Thread

Now that Kodak has pulled the plug on most 5"x7" Black & White film I could some help. I have been shooting T-Max and some Plus-X for the last ten years. Can anyone tell me what developers I might try with Tri-X sheet fi

Bruce: My favorite developer with Tri-X is HC-110. I like the brilliance of the negatives and the contrast in the shadow detail with this developer. Also, D-67 is an excellent developer. You might also try T-Max RS, which gives good results. Don't use regular T-Max as it leaves a scum that is difficult to remove. I rate Tri-X professional at 160 and develop at 68 degrees for five minutes. Hope this helps,

I find that using Rodinal at 1-25 or 1-50 and adding a few minutes more to dev time, and doing half as many inversions gives me good negs (although my inversions are slightly more vigorous than others). I've also heard that Paterson Fx-39 can give superb negs.

PMK Pyro and Tri-X.....just absolutely elegant!

Jon: I am planning to do some testing on PMK Pyro. Where can I get more info?

I have times for PMK on my site at:

You can use them as a starting point. I also recommend obtaining Gordon Hutching's 'The Book of Pyro' for all the fine nuances of using PMK.

Thanks for all of the responses. This is good information to know. I did have a question on the HC-110 for Doug. Do you use dilution B? Also I hear that Pyro can stain a negative. Is this true and what is the end result? Again thanks for the responses.
