My usual Canon gear with 100-400L lens handheld @ 1/1600, f/10, ISO 200, +1/3 exposure compensation.
Again, cropped for an 8 x 16 framing which I like. Horizon had to be straightened. Colour correction was a little dicey, there is still a bit of cyan/blue on the owl. I had to reduce an important amount on its right wing. But this is acceptable for me - you rarely find pure white in these situations in real life. Finally, too much colour correction to reduce to white would have destroyed much feather details.
Eyes slightly dodged to reduce shadow and bring out more of the yellow.
I deliberately avoided to add too much contrast and sharpening - this gives the owl a nice soft look.
Selective despeckling of the background to reduce noise.
Cheers,
Mike
