This is to me a very interesting snip
SLightly off topic - sorry - but I am convinced that most digicams I have owned roughen skin making it blotchy ie exagerating darker skin areas
These areas of skin probably contain more magenta than nice areas of skin
Are you saying that digicams in general are oversensitive to green (correcting this difficciency in the digital processing of the image)

In general, most camera sensors are most sensitive to green. For example, here is the spectral response function (SRF) for a [a href=\"http://scien.stanford.edu/class/psych221/projects/05/joanmoh/spectral.html]Nikon D70[/url]. When you take a picture of an actual scene (say a MacBeth Color Checker), the camera response to each color patch will be related to the sensitivity of the chip and the spectrum of the illuminant. Daylight has a fairly flat spectrum, whereas tungsten is deficient in blue.
Look at the white balance coefficients for
White Balance. Green has a multiplier of 1.0. To achieve white balance the red and blue channels must be multiplied by the shown factors.
