This photo is by James p. Blair a photographer for National Geographic.  I like how the focus for the picture is green with the green frog framed by the green lily pad and even the background is an off green color. When looking at this photo my eye follows the edge of the lily pad through the picture.  I also like how the main part is in focus and the rest is blurred.
