Blackened

Blackened was a test, to get very dark and monochrome, by using only a few lightsources, without getting noise in the final render. It is astonishing how few grey shades you could use in the diffuse channel, to get the correct value. The range goes from 1 to max 20 or so. Should the rest till 255 really be wasted? Please send me an email, if you know the answer.
