It already is, as I realised I'll need to take into account "gamma"
correction which really throws a curve into things. (literally <g>)
Probably why my numbers seem so conservative to you in the first
place. I use a "gamma" of 1.8, so you can factor that into your
perspective. The conversion formulas I have, assume a neutral gamma
or a linear RGB. So I need to figure out how to influence the value
correctly over the curve of the gamma affected values. Hopefully
there's an influence formula for gamma which is readily available. I
knew it looked too simple to begin with. <g>
