Just out of curiosity, does a black light show up on video? What does it look like? Maybe I should rephrase that by saying the RESULTS of blacklight... Can you see the purple colors on white shirts on camera?

The fluorescence will be picked up by the camera since it creates light in the visible spectrum.

Not surprisingly, YouTube has something!
