...xray film....

an examples of a scene shot on Xray green sensetive film. Developed with normal black and white chemicals. I shot this at a ISO 100, but have found similar results shooting at ISO 400. A lot depends on how long you develop it for, and what concentration of developer you use.

This is another example of Xray film, only reversed processed.

Interestingly, these films have emulsion on both sides. I think if you expose one side of the film at ISO 400, you technically expose the other side 1 or 2 stop under. So you tend get saved on the highlight details. on the flip side, the shadows probably gets blocked up. The images do seem a bit soft under a loup, another effect of the dual emulsion layer.

Have to do a bit more experiment.
