Pulling kodak tri-x 400?

[Peter de Groot]

Hi,

I have been looking around but could find a satisfying answer. I shot a roll of tri-x 400 but I have been measuring light as if I was exposing it on iso 160 (what I normally do). Do need to push or pull it? And by how much do need I to change the development time?

Thanks a lot.

Some will invariably say to develop it as normal since Tri-X handles overexposre well, but if you're using D-76 1+1 at 20C and want to pull it, digitaltruth.com says that for ISO 200 to develop for 9.5 minutes. I made a similar mistake about a year ago, except that I mistakenly exposed Tri-X as if it were 100.

Thanks. I forgot to say I use rodinal 1+50 and normally I develop a roll of film for 8,5 minutes.
I overexposed the film 1 stop. So I should develop it longer? I thought shorter. :confused:

One of my camera bodies calls for that EI and i use hc110 "b" at 6 minutes. which is my normal types for ISO 400

The MDC calls for Tri-X @100iso for 7.5mins (rodinal 1+50)and 200iso for 9mins, I might try it for 8=1/4mins then(averaged time)for 160iso. Looks like your normal time will is almost spot on.

Hi,

I am a dumb*ss! Rereading my first post I see I was really incomplete with my info. I'll try it again.

I shot a roll of tri-x 400 at 400 iso in camera. I was using a pentax spotmeter f that I set to ISO 160. Normally I develop my films in rodinal 1+50 at 8,5 minutes. However since I have overexposed my film this time by a bit over one stop how do I adjust my developing time to get the same (more or less) results as to my usuall routine?

I hope i made myself clear and apolagies for the confusion.

It depends on the light you shot it in more than how you exposed it. If it was very contrasty light (e.g. dark shadows and bright areas in the same shot), and you overexposed, you will probably benefit by underdeveloping by at least 25 percent, and maybe more. If it was a "normal" brightness range, or a little contrasty, and you overexposed, a 15 to 20 percent pull would probably work well. It it was flat light, but not too flat, I would develop normally. If it was extremely flat, I would push one stop. An overexpose-overdevelop technique really adds snap to pix shot in very flat light, and makes printing them much easier.

Thanks for the feedback. From all of you. I will give it a try and let you know the results.
