This is my first hand held flight image with my new 600II. This Black Vulture in flight was photographed with the hand held Canon EF 600mm f/4L IS II USM lens and the Canon EOS-1D X. ISO 400. Evaluative metering +1 stop off the blue sky 35 degrees up from the horizon: 1/5000 sec. at f/5.6. Central sensor Surround/AI Servo/Rear Focus AF active at the moment of exposure.

NIK Color Efex Pro did wonders for the blacks. See here for a before and after animated GIF.
