This image was taken about 2 years ago at the Masai Mara game reserve.
On my final day there, we found Vultures feeding on a Gnu. It was a great chance to get some flight images.
20D sigma50-500@500mm F8 1/800 ISO 200 around 90% of FF.
Pretty cool pose and details. Must have been pre-lunch since he looks so clean. :) I like the idea of lightening the shadows a bit, especially the eye. Have you tried a pano crop?
Interesting comp, I like the tension in the capture. Very good detail shown and I prefer the proposed lightening,
you dont loose the right hand talons in the shadows.
Very intense image - well done to catch this nicely focussed. I think Randy's repost is good in showing more shadow detail. I not sure I understand the 90% of FF comment as the 20D captures a 3:2 format image so to get a square you need to crop away 30%.
