The Blackest Material 299
QuantumCrypto writes "Researchers at Rensselaer Polytechnic Institute have created 'the world's first material that reflects virtually no light.' This anti-reflection technology is based on nanomaterial and could lead to the development of more efficient solar cells, brighter LEDs, and 'smarter' light sources. In theory, if a room were to be coated with this material, switching on the lights would only illuminate the items in the room and not the walls, giving a sense of floating free in infinite space."

Not to mention moving us one step closer, possibly, to having a real Holodeck!

Contrary to popular belief, the best color for urban night camoflage is not solid black. Depending on the environment, it's either charcoal grey (for general hard-to-see-ness), or irregularly-patterned greys (to break up the outline of your body).

This stuff could be really cool for use in MRIs or other tight spaces that claustrophobics normally have to go into. It would give those that are normally afraid to be in small spaces the sense that they were in a vastly infinite space. That's pretty cool IMO.
I'd also like to have my home theater coated with this stuff, think about how large your house would feel! Even with low level ceilings.

Sine I posted, I realized there are some flaws in my model of the luminance dynamics and in the post-processing, so I have to go rethink that all. My film work was decades ago and mostly industrial anyway.
I wonder if the military already has some form of this material, by the way. Er, probably captured from a crashed saucer, of course. (cough)

I remember one summer night in Yosemite when my brother and I spent an hour lying on our backs on one of the approved boardwalks across one of the meadows taking in the impressive night sky. I was astonished at how "other than black" the peaks and everything else around us were compared to the blackness of Space above, when, without the clear night sky to compare them to, I would have sworn that I was looking at some "pure blacks" among my Earthly surroundings. I was impressed by the contrast that I would not have believed was there had I not seen it with my own eyes.
4x reflectors (Score:3, Interesting)
Each of the walls reflected 0.1% of the light.... so the entire setup reflected 0.1^4 (%).... or about 'nothing'.
Anyway... The real reason I posted here is there's a guy on Ebay selling virtual backdrops. He bought a whole bunch from one of the photography forumns, and then photographed them in- and cells a single chroma key background, with the CD of the other background. He's making a pretty penny
