Sorry, I was refering to the diffuse=ambient part of your statement, not
the rest of the formula, which I agree with.
There. Better?

Chris, do you use the ambient 0 setting with both MegaPOV and the
official POV-Ray?

Yes, when I use the official version (most of my renders are tests of my
patches or require MP)...but I don't use the radiosity in the official
version, just a dim (around rgb 0.2 or 0.3) light source at the camera
position.
