First time I've come across this - shooting H4D-50 - I've got an amazing shot, but started screwing with it. Shot was set to Daylight - 5500K, and got the blue'ish image. Scene matches what I'm seeing with my eyes.
I auto white balanced against a building I know, and the color temp went to 47,000K. Um, ok, this is amazing, pushed 1.5 stops. 47,000K??? Didn't know it went that high...
Pull it back a bit, and while it looks kinda natural, I'm really impressed. I guess I need to look at other photos and see how they react to such an edit.
