Also you can use a regular camera, if you don't have digital, and then scan them from the prints. (OK the long way around, but it works)
I have also found that digital images have a reaction to the UV and make them different colors.
Now when is someone going to mount a UV tube in their scanner?

Real photo, 1/4 to 1/2 second exposure with almost no ambient light, works well. I did a series of bracketed shots and found that over 1/2 second you start to get flare and distortion, under 1/4 second the images are too dark. The best were taken at 1/2 second, f2.8 with a 10 watt UV light.

This is a digital picture using both daylight and UV mix. Luxor of course.
