Alligator, Okefenokee National Wildlife Refuge, GeorgiaIt was late in the day and the colors of the swamp were intensifying as the trees were reflecting off the surface of the water. The perfect time to photograph half-submerged alligators in the Okefenokee National Wildlife Refuge in Georgia. Nikon D300 with Nikkor 200-400mm lens (at 400mm) ISO 800, f/5.6 at 1/100th of a second.
