Flashlight Enthusiast
I just got back from a friends house tonight, and we were watching a taped episode of CSI...i think it was Monday's episode.
Anyway, about 10 minutes into the show, they had a scene where investigators were combing the scene using UV LED flaslights. What was interesting about the lights, though, were what was attatched to them. They had some kind of reddish plastic filter attached above the flashlight, so that the UV can illuminate the surrounding while the investigators look through the "window-pane" filter. I don't know what it did exactly (because i was playing PS2 while it was on), but i did catch a glimpse of it turning everything into a "negative"...if you know what i mean.
Pretty interesting stuff...do you know what it was?
