Good angle, exposure control and details. I also like the colors of the water. If it were mine, I would crop a bit off the bottom since the reflection is a bit blurry anyway, maybe just above the 'third bill'.
Its mainly been said, but superb exposure on this guy, with bill saved, yet good detail in blacks. Nice eye
Striking colors in the water. Agree with Axel re: crop.
I think the shooting angle is pretty good. Lower would have further degraded the reflection, and of course there is always the concern of something undesirable showing up in the background.
Love the bg and great exposure job and I know that Coots are difficult because we have lots of them here and I like watching/trying to catch their antics.
Christian, good low angle, and well done on exposing the blacks, as these guys are difficult. You have done well with the white of the bill too. I agree regarding the crop from the bottom, and what a great BG too.
Thank you all for your comments,
Axel and Stuart I also agree with the crop of the bottom, it balances better visually too (I did not post a new version, just scroll up to physically crop it...)
