Hope you dont mind me saying this but your WB looks slightly out on quiet a few of your shots lately,i downloaded that great shot of a duck in flight and upped it about 5/6 and on my monitor it looks better.
I don't mind Mike. I changed some in my processing so it's possible there's something going on I myself hardly notice. If you don't mind, feel free to post that shot so I can see the difference. This swan I deliberately lowered some values because I wasn't that much interested in the bird. I first had her white but it was standing out too much.
But it's possible I changed something or my monitor calib changed. It's a Mac; they do what they want, not necessarily what I want.
To add: I just checked some of my previous shots here and they're indeed all a bit to the dark side. Besides those of this afternoon, most are at least -3EV shots which might have something to do with it. I notice they're darker but if something else is out of order, you'll have to tell because they look reasonable ok color-wise. At least what I see on my monitor.
