Do digital sensors have a "native" lighting source or illuminant?
May 22, 2012

"Native" in this context is meant in a similar sense to the native resolution of an LCD monitor or TV screen - where selecting a non-native resolution can give poorer images.

The question is prompted by the thread "why do we care about WB?" where one gets the impression that a subject can be snapped in candlelight but with the camera WB set to cloudy or 7500K and the resultant mess fixed just moving a slider!

I would thought that sensors and their filter arrays are designed for optimum performance in a specific "native" lighting, e.g. illuminant D65 - or D55 or whatever - and that any other lighting will give less than optimum color rendition even if all the colors have been pulled in whatever direction(s) are needed to restore a good color balance
