Nikon F5, Nikkor 24mm f2.8, FPP x-ray film, Df96 for 4 minutes.
This film is finer grained than I thought it would be, but I suppose resolution is kinda important for x-rays. It is contrasty, and renders things in an interesting way. Only sensitive to blues and greens, and the van in this image was a sort of rust red - which it very definitely darkened. Will certainly give this another try. Developed in Df96 for 4 minutes at 74 degrees.
