Okay, so I learned in physics class (some may not know this), that light is part of the electromagnetic spectrum. Its the visible part, but right below it in the invisible part is infrared waves, and right above it is ultraviolet waves. I've seen some infrared photography, and its super cool. Its definitely something I'd like to do someday. BUT, is there anything on the other end? If you can take photos of non-visible light, would this work at the other end of the spectrum, in the ultraviolet category? I guess in theory, with the right sensor, you could pick up any sort of radiation, whether AM radio waves, or gamma rays (might want to get out of the way of the latter, unless your Bruce Banner, though). So, is there any Ultraviolet photography out there? Or is it ugly and not worth taking a photo of?
