[QUOTE="Mr Magoo, post: 466287, member: 3008"] Yes. This is what I believe happens also. But I never liked physics. Absorbs then releases at another wave length. From the readings I have read, and this is only since Theduke raised the question. You need a very pure wavelength of UV to capture the returned visible light. Any stray visible light will pollute the image as long exposures are required. Although I'm not totally sure this is the whole story as a few mentioned the filter you spoke of and full spectrum cameras. :/ [/QUOTE]
