I would like to see what you think about the dark background?? I made this image around 11 am at Ding Darling, I was trying to play with a few diferent things so I stacked a 1.4x and a 2.0x to a 600mm and had to take some light away not to blow the white on the spoonbill.
Canon 1DMkIII
600mm with 1.4x and 2.0x
Iso 400
F10
1/250
compensation -2.1/3
I like the pose, colors and details but I think the BG is too dark, at least for my liking. Maybe you could selectively tone down the whites so you don't have to decrease the exposure for the entire image.
