Covering the results of experimenting with Kodak Tri-X 400, this article picks up from my original Kodak Tri-X 400 review and will show you single-stop pushes from EI 400 all the way up to EI 12800. It’s also been supplemented with part one of the High EI Shootout, which takes Kodak Tri-X 400, Kodak T-MAX 400, ILFORD HP5 PLUS and ILFORD Delta 400 to EI 12800 and part two, which takes the same films to EI 25600!
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 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 EI 3200, 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 IE 800 and go up one stop from there until we hit EI 12800 (five stops over box speed). Prepare yourself for a wall of pictures.
TRI-X at ISO800
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 EI 1600:
TRI-X at EI 1600
TRI-X at EI 3200
EI 3200 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 EI 3200 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 EI6400
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 EI 12800 – the final push
Here’s the final push, as it were. TRI-X pushed five stops to EI12800. 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 EI 25600 push on this film just to see what will happen. I’ve seen some great results from Ilford HP5 PLUS and Delta 3200 Professional shot at this speed, so you never know what you might find one EMULSIVE in the future.
As the last word from me, here are development times for Kodak Tri-X 400 as used/refined by me over the past few years for EI 400 up to 25600 in Rodinal and Kodak HC-110.
