Vuescan uses a different exposure per RGB channel to handle the color 
negative's orange mask. The green exposure time is 2.5x and the blue 
exposure time is 3.5x to the red exposure time. Sounds like a sensible 
approach that isn't used when the negative is scanned as a positive. Any 
comments on that in the Docs cited ?
