Sometimes you come across settings and situations where there just isn’t sufficient lighting to go smooth and grain free photography with reasonable shutter speeds and settings. Especially with living subjects, like people, you need to allow for some «life» in your model and hence use 4 seconds shutter speed. In these situations, an option is to push the film. However, when pushing film, you will lose some of the detail get increased contrast added to your images.
For this entry, I created a situation where I had very limited light, and I went for two 400 speed films which I pushed. My initial Idea was to push both of the two stops to 1600 and see what differences I could spot, but due to a change in lighting conditions, I had to do one of them at 3200, a three stop push.
Ilford HP5+@1600
My first film for this photoshoot was a roll of Ilford HP5+ Medium format film. This is a film I regularly shoot, and I am very familiar with the characteristics of this film at both 400 and 800, but I have never pushed it further than that before. Therefore, I was curious how it would deal with the extra stop of push, both in terms of grain and contrast.
The only lighting used for this shoot was the available light in the old derelict class-room and what I could reflect back using the «sunfire»side of my reflector. I shot as close to F4 as I could and got shutter speeds around 1/60th of a second.
I was surprised to see the negatives when I pulled them out of the tank. I expected a very punchy-looking negative with a substantial lot of contrast and severe loss of detail, but the negatives looked reasonably good. The push was obviously visible, but not as prominent as I would have guessed. My quick scans also turned out some nice images. Although grainy, I like the look of these pictures.
I see that I got a bend mark on one of the images, I clearly was a bit unlucky when reeling the film for development.
Kodak Tri-X400@3200
If I expected grain and heavy contrast on the HP5+, I did not expect much of the images from the three stop pushed one. On my way home, I actually doubted my move and was already drafting my apology letter to the model, who friendly joined me for this experiment. I was, however surprised in two different ways.
Even though I followed the guidelines for a three stop push found in the massive dev-chart and had fresh and well tempered chemistry (20 degrees) some of these negatives came out very thin. I metered in the same way all the way through the shoot, and I obviously developed the whole roll at the same time so the big difference surprised me. I must have made a mistake with my metering at some of these images.
However, some of the negatives looked really nice. Although they were obviously very contrasty and punchy they looked to have kept at least some of the detail I looked for. As you can see in the pictures the push is very visible, and I would not go for a three stop push if it could be avoided.
This shoot was a real gamble, and I am thankful for the model who helped me on this. Although I couldn’t really compare the two films because I had to do different pushes, I must say that I am surprised how well both films coped. However, I would say that the grain and latitude of the HP5+ appeals more to me than the TRI-X. But this is a personal observation.
I have decided to try out these negatives in the darkroom at some point, and I will post my results and workflow from that at a later point.
