Canon MarkIII with a Canon 500mm f/4 IS lens and 1.4 converter@ f/13, 1/1000, ISO 500. Levels, S/H, saturation and sharpening in PS. Small branches at bottom of photo were cloned out.
Louis:
Very nice wing and tail display.
There are some hot white areas, which can be toned down with the recovery slider, although I suspect some detail has been lost.
For my taste, the contrast in the image is too high, which worsens the hot area issue, and the sky a bit over saturated.
I tried a small reverse s curve adjustment after doing recovery, and it did soften the contrast and lowered the saturation a bit in the background.
There are some halos around the bird.
I might give it a little more space to breathe in as well.
The pose and sharpness look good. I would desaturate the sky a few points and run NR on it. Some of the whites of the bird are overexposed, I hope you can recover them in your RAW converter.
