Mark off at 1 meter, 2-4 meters, 4-6 meters for the settings on the Diana (or your favorite lomo camera) or put a mark on the string at every meter for setting the focus between the presets on the camera.
See how easy that is. Stunning, i know. All you need now is a way to keep the string together. If only you had a small light weight container to put it in. Oh, hey i can use the film container from any 35mm roll as simple storage for this mod. Wonderfully simple and wonderfully useful.
I am going to try and post some home made splitzers here soon and some shots taken with it.
