Originally posted by kengoh Thank panoguy, you are right, the background is a dull white/grey sky.
The bird is almost black. I just like this action shot so try ways to preserve this pic, can't hide from your yrs of high-end fashion retouching skills.
It's an excellent moment in flight of a very colorful bird, so I would be trying just as hard to preserve it (although I'd struggle with the focus and tracking long before this - I'm not good at BIF).
It really wouldn't take that much to "integrate" the bird better with your chosen background... "Feather" (ha!) the mask around the body and slightly around the feet (but maybe not the beak) and "brush-out" the mask (more feathering done with a big, blurry brush) where the wingtips are in motion or at the bird's feathers edge, then brighten & desaturate (a lot) the area behind the upraised wing, and darken the area at the feet and tail.
Really, it's just about "selectively" lowering contrast and edge sharpness on the macro level... (easy for me to say, right?) and matching the expected backlighting for those luminous wing feathers.
Adding noise to your background might also help, but might not make as much of a difference since we almost expect to see smooth bokeh.
Well, anyhow, sorry I rambled... like I said, old habits die hard.
