Kate, I've found that Cyanotype absorbs effectively into film that still has its original gelatin on it, that is, already processed film or clear leader that is just fixed and still has gelatin. Just soak the film in cyanotype solution, and let it dry in a dark place. But as Brian says, it's EXTREMELY slow, and what passes for developing it does not, as with silver halide film, amplify the exposure. Only exposure to light can create an image on it, and only blue -- ultraviolet light at that. This means that you can work with it in incandescent room light, and not worry about flashing it, but it also means that it needs exposures of a minute or more in full sunlight. It works for contact prints. To use it in a camera, one would need to expose each frame for something like two minutes. Which might be very interesting!
Good luck!
