I was setup for another scene when this Great Egret surprised me when it appeared, low enough, from right over the nearby tree line. It surprised me even more when it angled to fly over directly above me. No time to adjust settings - shoot now, ask questions later. The image turned out to be quite over-exposed, but being white-on-white it was rather easy to tame in post by darkening parts and adding saturation to others. I also clipped the wingtip to our left so I added canvas, re-cropped to taste, and borrowed feathers form the opposite wing (and tweaked so they were not perfectly mirrored). I am happy with the final product, hope you like it!
