There's a tree beside the house I used to live in, and in this tree some eagles roost. Last spring I managed to catch one as I was heading out the door. 2 minutes into my car ride, I realized I had forgotten something, so I came back. When I looked up, there was another eagle, but this time it was doing something curious. I zoomed in... Yup - meal time. ;)
Processing this was tough - the feathers blend into the tree, and it was all back-lit. The crop helped, but I had to use a radial gradient selection applied to some levels, curves and hue sats to bring out the eagle in the middle without losing too much detail. Wish my hands were a bit steadier - this was the sharpest one I got.
