Every Summer when I go to the beach I walk a few miles at night looking for sea turtles who come on shore to lay eggs. I was by myself this night and found one just before I was going to turn back. There was no moon this night so it was extremely dark. The images of the sand and nest are about a two minute exposure and the turtle crawling to the water were shot at f/1.4 at 3200 ISO 1.6sec. exposure; explaining the grain and motion. The light coming from down the beach is light pollution. Hopefully I will make it back to the beach to see the eggs hatch.
