Tis photo was taken by Alex Maclean. He uses natural light in this photo. Due to the natural light there is both high light and showdows created by the dried cracked Earth in the top center of the photo. This photo was taken from the air. The photo is asymmetrical. Right away i can see that there is a natural rule of thirds created bythe land then the land and the water, and then there is the ocean. when i look a this photo my eye is draw to the thop right coner where the ocean is its bluest blue. Alx Maclean took this as a horizontal photo. this is very effective because because there is a wider point of view.
