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."

to say something "reflects no light" does not mean it "absorbs all light"
you are leaving out transmission of light. If a material does not reflect light, it either absorbs or transmits all the rest of the light.
which is actually what this article is talking about
this was quite an errant post as it is both a dupe and factually flawed.

Maybe not, but they're both electromagnetic waves (though with a very different wavelength). So the question may be relevant.

if you're talking about the key color spilling into the subject (like in between hair and such) than that's a different issue. that's why when you do a telecine, you'll do what's called a "suppress pass" which desaturated all of the key's color. that way you can comp the original footage minus the key color back into the comp to kill the color spill without having to hand-draw it into each frame.
i'm sure it could be used for some pretty interesting techniques in photography and film but color keying isn't likely to be one of them.
