Well, you don't need me to explain this, do you? (As usual, you get better detail if viewed on black).
Many thanks for all your recent comments. I appreciate them all.
(For all those that might have a view or an interest, I believe this shot is a classic example showing chromatic aberration, especially obvious when viewed on black. Any hints/tips welcome, as I did try and correct this in Lightroom but obviously failed miserably!).
It's a hard one to avoid when you are in a high contrast situation. Lenses are simply not as good as the human eye for creating balance in these situations. I will be interested to see if anyone can offer any solutions. I love him as he is though - cheeky face and the light makes it look like a pre-breakfast sunrise dip ;)
