First try at pushing Tri-X

[ray_g]

I have settled on APX100 as my slow speed film, and Tri-X for medium and fast film. Based on postings on RFF, with info mainly from Gene and Merciful's techniques, I tried my first test roll of TriX at EI 1600, developed in Rodinal 50+1.

Thanks for sharing your knowledge, guys!

This was taken with a 50/2 LTM Nikkor at F/2, 1/60 i think, on a Canon P.

I've never tried Tri-X on Rodinal...wow, it never even ocurred to me! What is the dev time for 1+50? btw, nice melody! You sing too?

Looks good to me Ray ! :)

Tri-X is also the fastest film in my bag when used at 1250 with Diafine, but I agree that Merciful, Gene, and now yours shots with it in Rodinal look real good.

Tri-X in Rodinal ... music to my ears :) Welcome to film abuse and it's all legal :D

[ray_g]

Thanks.

Gabriel, I just followed the recommendations of others on the forum. For 1600 iso, the development was 22min at 68deg, agitated for the first 30 sec, then 5 inversions every 5 minutes.

No, I don't sing. I just listen to my wife play, usually while I am developing for 22 minutes or longer :)

Ray,

Didn't you get some Diafine not long ago? 6 minutes total. 7 if you count pour times. 9 if you count fixing too.

I can't imagine standing around for almost half an hour messing with developing film any more.

Tom,

No, I haven't had the chance to get or try some. The shorter dev time certainly sounds appealing. I'm brand new at this, though, so I don't mind.

I also very infrequently push. And with what I have read about Tri-x and Rodinal on this forum, it seems I can push the TriX to much more than what Diafine will allow.

I'm sure that eventually, I will also get myself some Diafine :)

Hey, that's lookin' really good, Ray! I've been experimenting recently with pushing Tri-X with HC-110 diluted 1:100. I've had some luck with that -- I'll start a thread on it in the next day or so.

Really? What is the max tri-X/diafine push? I exclusively use diafine for my tri-x and save rodinal for apx-100, but if I can get decent tri-x results with a 3 or 4 stop push using rodinal it might be worth the hassle of not using diafine.

As I said, I haven't used Diafine myself, but i believe it increases the speed of Tri-X to 1250 (or 1600). For Tri-X and Rodinal, you may want to read this thread:

Not that I need pushes that large. I will try diafine someday, but right now I already have the rodinal for the the apx100.

While Rodinal is a fine developer and looks lovely on Tri-X, it is unlikely the best choice for pushing. I don't have access to Diafine here, but the scans from Tri-X @ 1250 or 1600 processed in Diafine IMHO exhibit very few pushing artifacts (grain, contrast, loss of detail), if any. Or try speed-enhancing developers; Tri-X in Microphen feels like 600 ISO and pushes well.

Here is a recent Tri-x push to 12850 Rodinal 1:50 @68 Degrees 51mins 5 sec agitation every 30sec.

[Skinny McGee]

Well I was trying to get one the photos on there I 'll try again

Under normal circumstances that's true, but this is a modified stand development technique that changes the normal equation. It's experimental, and probably not to everyone's taste (is anything?) but the results are interesting and not what one would expect.

I admit the example looks fairly good for 12K ASA. Perhaps should try that someday.
