Something important to think about in color images: warm tones (the land in this image) contrasted with cool tones (the sky) creates separation and depth. This entire image was globally desaturated by about 50%, with the blues and oranges selectively resaturated to approximately +50%. Color is more saturated in the center of the image than it is on the edges which helps direct the eye, letting the eye wander around but always bringing it back to the center. These are subtle changes but apparent when you understand the manipulation of color. Similarly, selective contrast is greater in the center of the image than on the edges which has the same effect on the eye.
