This is my first attempt at making a split-exposure image with one of my pinhole cameras. Of course, I made several major blunders!
I created the effect with one of my rectangular foam board pinhole cameras by taping a piece of black card over about half of the photo paper in the target area. I posed in the light and stood still for about two minutes – the camera was set to do a vertical (portrait) oriented image. I left my sandals in place, unhooked the camera from the tripod, ran into my darkroom, moved the card to cover the other half of the photo paper, and then ran out to renew the photo session. By leaving my sandals and the tripod in place, I was able to maintain continuity between sessions, pretty much.
For the second session, I jogged in place. The intended effect was a sharp image of my upper body with a blurred exposure of my legs below. A colleague at work had shown me some interesting pictures of this type a few years ago that he had made with a digital SLR and a very clever shutter device he had fashioned. Mine was to be much more crude, of course.
Well, for some reason I imagined that the split in the image, clearly visible in the positive above, would be at waist height. This despite the fact that I had set up the camera so that the pinhole was nearly at eye level! Bigger mistake: I forgot that the image on the exposed paper is inverted. Thus, the first exposure session, which was supposed to capture my immobile upper torso actually imaged my immobile lower body. In the second session, when the blocking card was shifted, instead of capturing my moving legs that were jogging up and down, it captured my upper body which moved less vigorously, but still very noticeably.
Hmmm…still sort of interesting, but I think I will try again, the RIGHT way, tomorrow.
