Does Tri-X 400 become grainy when pushed to E.I. 1600?

Discussion in 'Black and White' started by k_michael, Nov 13, 2002.

  1. I used Tmax developer to develop the film and I think it came out grainy. I'm looking for some feedback on this. I was forced to push the film because the event I was at barred the use of flash.
  2. all films become more grainy when pushed. especially two stops.
  3. You have to expect two things when you push film with extended
    development: increased contrast and increased grain. The graininess in your
    posted image looks pretty good to me for a 2 stop push of Tri-X.
  4. Yes, Tri-X will 'grain-up' when pushed. Yes, it's capable of EI 1600, although 1250 is more like it.

    TMAX developer is mediocre enough with Tri-X at rated speed....pretty bad when pushed, which is bad^2. Get yourself a can of Acufine if you wan't to see what Tri-X is REALLY capable of at the edge of it's envelope.

    Personally I think Tri-X at EI 1250 in Acufine looks better than processed in TMAX developer for EI 400.
  5. I've pushed several rolls of Tri-X to 3200 in straight D-76. The grain and contrast are actually pretty acceptable, so I keep a roll or two of Tri-X as a backup to my normal film (Neopan 1600) when shooting concerts. At 3200 Tri-X gives much better results than TMAX 3200 at 3200. Go figure.

    All of the shots at these two sites were shot using Tri-X at 3200.

    Actually, that's a lie...several of the Frames shots are on Delta 3200. I can't tell which ones - can you?


  6. I did this one at 3200 and developed it in Xtol 1:3. Visible grain? Yes, but pretty fine and not detracting even when enlarged to 11x14. I shot a roll of Tmax 3200 at the same event, developed it the same way. It was much more grainy than the Tri-X was.

    what temp and time did you do tr-x@3200 with xtol 1:3? around 25
    minutes? is it very different than say xtol 1:1. i would like to try
    if there's a big difffent. i can't find the time nor do i like
    develpoing more than 20mins for a roll though.
  8. Tak-Fu - I used 20 minutes at 20C. Check out the massive development chart at This is the only place I know of where the development times for Xtol 1:2 and 1:3 can still be found. Kodak deleted these from their data quite a while ago. Despite what Kodak says, I've had the best results using the 1:3 dilution, not just with Tri-X, but also with Tmax 100 and Ilford Pan F.
  9. The times for new Tri-X in Xtol are about 15% longer, guess why that is.... This means about 23 minutes in 1:3 Xtol in comparison to the older Tri-X pan. Xtol is the best choise for pushed TX IMO. Good tip... Anyone tried mixing xtol with rodinal when pushing BTW?

  10. I haven't tried pushing with the Xtol/Rodinal combo, but my current "standard" development for Tri-X is ei 200, Xtol 1:3 with 4 ml of Rodinal. This was from a tip by Scott Eaton.
  11. I can also recomment Tri-X pushed and run in Microphen. This
    is my favorite push developer. I shoot Tri-X at 1600 and 2000
    regularly and dev it (in Microphen) at 13min and 16min
    respectively (both at 20 degrees C). I really like the results here.
    Grain is noticible, but still quite acceptable, IMO, and contrast is
    better than it has any right to be with this much pushing. Give it a

    Grainey? That depends. If you assume Tri-X is ISO 400 and you push it two stops to 1600 you'll see a lot of grain. If you meter Tri-X at ISO 160 and push it two stops - to ISO 640, then the grain is not so noticable. But ISO640 is kinda slow for push processing, you'd be better off the push TMAX400 two stops (and meter it at 1000). J. Michael
  13. i regularly just push my tri-x to 6400, instead of using a 3200 film. i like the results better. i mlearning muc more aobut what i can do with tri-x by using it in most situations, instead of switching film.
  14. Andrew, are those times for rotary or manual development? Condensor or diffuser? I'm about to try Microphen and Tri-X as well.

    And Michael, what developer have you used to get this excellent tonality?

    best regards
