Photographers go to great lengths to make order out of chaos. A good photograph has a strong point of view, clean lines, generally good composition. In this case chaos IS the point. Anyone who has ever witnessed a flock of snow geese erupt into flight knows that the sight and sounds of those birds says chaos to the extreme.    This flock was photographed with a 200mm lens, 2x tele extender, Olympus E-5 camera, 1250/sec. @ f5.6. ISO 200. The scene was made at Blackwater National Wildlife Refuge just after sunrise, thin cloud cover.
