X-ray "photographs" are not photographs in the usual sense they are really
shadowgraphs or "Shadograms" or "Rayographs" or photograms or whatever
you call them i.e. an image is not formed on the film but a shadow. X-rays are
absorbed by different substances in proportion to their "density." Bones
being more dense than tissue, for example, will be lighter on the "X-ray."
Optical filters, which are designed for the visual portion of the E-M
spectrum, would probably have little effect on X-Rays.
It might be possible to design an X-ray camera that would use a "lens"
made of aluminium, or gold maybe to form an image but iy would use
reflected x-rays. Antway there is a better way, I believe it is called
a CAT Scan.
Hope this does not dicourage you from creative thinking.
