Chances are, if you're into film photography, you've at least heard the terms 'pushing' and 'pulling' film. In a nutshell, you take your film and meter for light over (pushing) or under (pulling) the box speed of film. There's an excellent breakdown guide here: The Darkroom
I have quite often shot both Kodak Tri-X 400 and Ilford Hp5 at 1600 iso. It gives a bit more versatility when shooting in low light, or trying to capture faster action. I had a fair bit of film sitting in the fridge, so I decided to see what would happen if I pushed Kodak Tri-X to 3200. I need to further refine my development times, but I'm pleased with the results.
There doesn't seem to be a lot of info online about pushing Kodak Tri-X to 3200. After shooting the roll, and then searching for a while to get some guidance, I came across a solitary post with a few suggestions. I can't recall what website it was on, unfortunately.
I developed using Kodak HC-110 with the following method:
- 22 minutes @ 21 degrees Celsius
- 10 inversions every 60 seconds
- 60 second stop bath (Ilfostop)
- 5 minutes in fixer (Ilfofix)
- Rinsed using the Ilford method (fill tank, 5 inversions, empty and refill, 10 inversions, empty and refill, 20 inversions)
I think it could benefit from another 60 seconds or so of dev time, but not a lot of extra time.
This won't be my last attempt @ 3200!
