E620 Auto WB problem
Just as you wrote, interesting.
About men using blush? Well, nothing that I fancy. Not to my taste
Now, some more serious talk, about the E620 settings. Here on Portugal, where the sun is harsh, those are the settings that give me the more correct colours for our skin tones. Keeping the colour muted, my camera gives me better reds and greens.
But, I accept that for other latitudes, where the light intensity is much different than the one we have here, your settings might be better.
In any case, the E620 has always been one of the worst cameras (of those I have or had) to give me the correct colours.
