"lookup value = intensity to the 1.0/y (where y/gamma represents the nonlinearity of the monitor…. << This is like gamma 101. I totally understand gamma as it relates to video. You tell me the kind of camera you're using or any non-linear output device for that matter and I can calculate what the gamma needs to be, applied to that device and correct for the NTSC monitor so that it is linear. 3DS output through a linear device without gamma correction like an Illuminator Pro in YUV should be 2.2 amount of gamma applied to the rendered image to be correct. It is not. The default *lighting* is too hot or the way 3DS is applying gamma is not standard. It matters little which the case is, but I need the formula to be able to calculate what gamma value *needs* to be applied regardless of how its being applied for a given RGB value to calculate correct video space. Thanks, John
