Out of interest, is the green under its chin a result of trying to get light/histogram levels correct, or was it really "there".
I often have trouble with over-exposed areas picking up a green or blue tinge when corrected.
Thanks. What's worse, is that I lost quite a few attempts to this problem today: white gulls and the like, against dark backgrounds. Trying to remove over-exposure just leaves a vivid green discolouration,
