Ring-necked Duck

Pretty standard duck frame, but I hung onto it because liked the highly-reflective and glowing-green water. This frame resulted from the same pass which generated the adjacent lime-peach frame, but I reflected it so the subject is swimming the R to L instead of L to R, purely for variety. This frame also has slightly better exposure/detail in the blacks on the chest and face (1/1600 vs. 1/2000), so there's that as well. I'm just happy I was able to alter the exposure by 1/3 stop as I panned with the swimming bird.
