Experimenting with Kodak TRI-X from EI 800 to 12800


This article picks up from our original Kodak Tri-X 400 review and will show you single-stop pushes from ISO400 all the way up to ISO12800. It’s also recently been supplemented with part one of the High EI Shootout, which takes Kodak Tri-X 400, Kodak T-MAX 400, Ilford HP5+ and Ilford Delta 400 to EI12800 and part two, which takes the same films to EI25600!

All the images featured in this test were metered with the same Sekonic L-308S light meter using a reflective or incident reading, as required.

 

Got a few hours?

There’s almost to too much to talk about here. I shoot TRI-X in both 35mm and 120 formats and it’s one of the films I carry with me every day (I’m normally walking around with one or two rolls ready to shoot and five rolls loaded in the day pack).

I have the added luxury of being able to develop my own black and white film. One of the (welcome) side-effects of being able to control my own developing process, is that I’m pretty much able to mess around as I feel. Couple this with my zen-like approach to BW development and the results can get “interesting”.

As I’ve mentioned already a few times, this film is incredibly flexible and will lend itself to almost every lighting condition. Whilst it handles very well in mixed light up to around ISO3200, my experience is that if you find yourself in low or failing natural light, you should over expose this film around half to one stop for the ISO you’re metering it at. If you happen to be indoors with artificial lighting, simply meter for the subject and you should be fine.

If it’s your first time playing around, I’d really suggest bracketing your shots so that you can compare later.

Right, let’s see how far we can push.

 

Pushing Kodak TRI-X 400

We’re going to start by pushing this film one stop to ISO800 and go up one stop from there until we hit ISO12800 (five stops over box speed). Prepare yourself for a wall of pictures.

So far, so good. Pushing the film has naturally bumped the contrast a little. When push processing black and white film I normally try to stick to a stand development with Rodinal at 1:50, or even using a highly diluted concentration of Kodak’s own HC-110. Let’s have a look at ISO1600:

TRI-X at ISO3200

ISO3200 is Kodak’s suggested limit for pushing this film. However we’ll see below that it’ll go much further than that. Let’s take a look at an ISO3200 push below. It actually holds up pretty well. I’m especially happy with the completely unexpected shadow detail in the second shot. Try doing that with a color film, whilst also pushing it three stops.

Pushing film needn’t result in blocked out shadows and super high contrast. If you’re careful with your metering, you can still get fine detail in the shadows.

 

TRI-X at ISO6400

So here we are, pushing one stop faster than the manufacturer’s recommendation. I find that if you’re careful, you can still get useable results. see below.

It’s pretty grainy but WOW. The first picture really blows me away. The camera I was using that day is unreliable but has a remarkable lens. I still look for faults in exposure every time I revisit this shot.

 

TRI-X at ISO12800 – the final push

Here’s the final push, as it were. TRI-X pushed five stops to ISO12800. I’ll be honest, I screwed up the development. It was a very grey and rainy day. No light, no fun. BUT the results are still useable, very useable in fact.

Next time I try such a high push, I’ll make sure I choose a day with a little more light!

And there we have it

We’re done.  There’s a small part of me that wants to try an ISO25600 push on this film just to see what will happen.  I’ve seen some great results from Ilford HP5+ and Delta 3200 Pro shot at this speed, so you never know what you might find one EMULSIVE in the future. As the last word from me, I’d like to invite you to view the images featured in this experimentation review, as well as Kodak’s Tri-X 400 technical datasheet below.

  1. These are compelling results especially in the higher end of your sensi scale. However, if I may, the real trick is the nature of the light ie under daylight you can indeed obtain amazingly good results at sky level EI, under tungsten light this is a completely different ball game from my experience.
    The film doesn’t have nearly as much sensitivity to yellowish light than it has to blue light, so exposing interior shots at 12800 will yield to far more equivocal conclusions and more importantly tonal separation …

    No bad blood wanted here, I do appreciate the work a post like this requires.

    Just grateful to have the opportunity to share a personal fustration with exposing high EI under tungsten light on Black and White film is all.

    • Alexis, thanks for the comment.

      Some really interesting points there. I actually shot that last roll at 12800 because of how flat/gray the light was that day.

      Whilst I plan on trying it again on a brighter day (today perhaps!), I hadn’t considered shooting at a high EI indoors AND under tungsten light until now. Great advice, thanks.

      Do you have any indoor high EI examples you can share? I’d be really interested in seeing them.

  2. I am wondering about the negatives themselves. I assume you are scanning all these negatives but do you feel they get thin with such a high push? When printing in the darkroom this might become an issue and make the negatives more difficult to print properly.

    This test inspires me to repeat the test for myself and see how I like the results, because I never scan and only print.

    Reply
    • Roy, you’re absolutely correct. At the upper limits of this test I found that the negatives became too troublesome to use for printing, so instead I’ve had to settle with digital scans and printing for my keeper shots. I’d be keen to see your results from a wet print at ISO6400 and up. Great website by the way!

    • Thanks! I just started very recently, so still in the process of writing the initial content.
      As soon as I have my results I will let you know via these comments or twitter! 🙂

      • That would be very much appreciated!

  3. Your shots are so inspirational. I LOVE the look of Tri-X pushed. What is the time that you use for the stand development for the Rodinal at 1:50?

    Reply
    • For ISO3200 it was 115min with 1 min initial agitaion followed by 20 secs about every 30 mins at 23c / 73f. Higher ISOs require much more time! 165min for ISO6400 and 225min for ISO12500. At the higher end, agitating every 10 mins will pull the time down to about 120mins!

  4. Hello,
    Wonderful article. Very much appreciate all you wok explaining the film.

    In the section, TRI-X at ISO6400, each of the three photo labels read, Kodak TRI-X 400 – shot at ISO1600. It should read 6400.

    • Thanks Bubba. I thought we’d caught all of those. Thanks for the keen eye!

  5. In order to push higher, shutter speed needs to be high ? My camera only has max 1/1000 shutter.

    Reply
    • First you need to set your camera or meter to a higher ISO. From there, either higher shutter speeds, or smaller available aperture can both help.

      Let’s say you’re shooting during the day time and have your meter/camera set to ISO 1600. Your camera tells you that you can shoot f8 + 1/500. If you want to shoot at ISO 6400, you need to increase your shutter speed two stops, or make your lens aperture smaller. EG: Two stops more would mean you could shoot at f8 + 1/2000, f11 + 1/1000, or f16 + 1/500. You just need to make sure that you shoot the entire roll at the same ISO, as well as push it in development.

      Hope that helps.

  6. What’s your stand development time with rodinal 1:50 for 1600? I’m stand developing with rodinal at 1:100 for 90min and digging the results but I’m interested to try 1:50..

    Reply
    • Hi Brad, sorry about the delay in replying to your question. EI 1600 in Rodinal 1:50 at 20c would be 29:00 based on 1 minute of continuous agitation followed by 5 seconds each minute thereafter. Hope that helps and please share your results!

  7. Would love to push T-Max to this value and see the results. Have always found the grain to be finer at 3200 vs Tri-X.

    Reply
  8. I’d love to see more night shots using this approach. That’s where most would shoot 1600 > and reckon this is where we’d see if it works.

    Reply
    • Based on what I know, most regular night, or low light shooters will shoot at box speed because reciprocity is easier to deal with. That said, I’m always up for a challenge and will give it a shot (literally), as soon as I can get to it. Thanks for the suggestion, Daniel.

  9. Thanks for sharing this. It was really helpful. I ll be trying this on my tri-x 400 @ 1600. Thanks again.

    • You’re very welcome indeed. Did you see the EI12800 and 25600 articles?
