Or did I read that backwards?
If their skin comes into play when metering, your camera could
underexpose light skin and overexpose dark skin. So you need to
compensate. But I've always thought this was more a black and white
technique. Does it really apply for digital imaging?
It's a principle driven by basic reflective meter response
calibration. Remember that a reflected light meter believes that
ANYTHING in front of it is an 18% gray average target. Makes no
difference whether you're metering for a sensor or a piece of film,
b&w or color.
Of course, some adjustment to how much you alter the exposure based
upon what the particular film/sensor response curve happens to be is
appropriate...
