For UV photography, you will need quartz lenses (quite pricey), a hot mirror filter that cuts off both IR and visible light (again, not usually cheap for something decent), and a UV sensitive film. The only film that I can recall that had a good UV sensitivity was Kodak EIR (yes it was a false color infrared film, but it was also UV sensitive). Since that is no longer made in 35mm format, you would have to get cut down Aerochrome III 1443. I know a guy that sells fresh 120 format Aerochrome III 1443, and if you are interested, please let me know.

I have not known anyone who has done UV photography outside of the scientific community (and more importantly, outside of getting government grants). It is expensive, but I have seen some impressive shots of the UV markings on flowers with Kodak EIR. Best of luck!
