>> Sounds like an interesting project… << 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>
