Full frame image of male peregrine falcon defending the nest whilst ringing under official licence.
The image was created under awful light and wind conditions on the roof of a 118m high rise building. This is a full frame image and when viewed large subject movement is evident. I think the overall image is however acceptable for an A4 size print or internet view in my humble opinion.
Canon 7D, Sigma 500f4.5 EX, ISO800, f6.3 , 1/1600sec.
Minimal levels adjustment and sharpening and selective noise control.
