    Do you miss TXP (Tri-X 320)?

    If so, TMax 100 might be your friend.

    By underexposing TMax 100 two stops at EI 400, and then push processing in Xtol 1:1, you will get results that are confusingly alike the venerable Tri-X 320 (TXP).

    One of the frames below is Tri-X 320 processed in replenished Xtol, and the other according to the recipe above. If I hadn't known which is which, I wouldn't be able to tell them apart. The sky changed between shots.

    Both frames scanned according to the same scanner settings, and processed together using the same changes. No individual changes, except overcoming the higher base fog of TXP by adding just a hair more contrast in the black on that frame.

    Grain, you say? Of course TXP will have more grain. But perhaps the sharpness of TMax will help you overcome your loss.

    Thomas, what was your time and temp for the pushed TMX?

    Pretty remarkable test.

    Or if you need more speed.... TMAX-400 can be made to behave like TXP-320. I expose TMAX-400 @ iso 320 and develop for about 7.5 to 8 minutes using replenished TMAX developer @ 1:4 dilution (68 deg f)

    I always shoot my TMax 400 at half speed and soup in Rodinal 1+50 for that creamy smooth look.

    I don't remember exactly, but I think it was 1:1 for 14 minutes, agitating every 2 minutes.

    That will not look anything like Tri-X 320, however. I'm glad that works for you, though.

    It's always nice with alternatives... If I were to do the same with TMax 400 (which I have done), I shoot it at 1,600 and process in Xtol 1:1. That gives me the same toe that Tri-X 320 had. I'm not familiar with TMax developer, so I just trust your eye that it works like a charm...

    The thing about Tri-x is that Kodak recommend increasing the standard developement time by about 30 to 40% for a two stop push. Check Ilfords recommendations for HP5+ and they recommend doubling the basic time and then some...

    One reason why Tri-X fans accuse HP5+ of being 'low contrast', I reckon, and the reason why I managed to get Tri-X negatives too dense to print....

    Can't help you with long toes and straight portions and stuff, I ain't that clever, but try giving it a nice looooong soak in some hot, undiluted stock developer just to prove you can get all the contrast you want (and a lot you probably don't ;-)
