greenish tint in photos on cloudy days?
I've noticed a green/blue tint on almost all photos taken on cloudy days -- which, I just discovered, I can get rid of by editing & selecting "revert to original" (without actually doing any editing). So I surmise there is some misdirected auto "feature" that turns things green on cloudy days (colors are fine on sunny days). What might that be? What do I want to turn off (or on)?
TIA, Pete Tillman
