I’m gonna keep this very short. Its a thought that have gone thru my mind several times and i might as well share it out here.
Why does the rules of third works?
I believe its simple because we will identify faces automatically and we look for the “eyes” as the location on the face, which happens to be 2/3 up there.
In short, regardless of a scene or object being shot at, the eyes feel more natural looking at things located 2/3 of the picture. If you put a face in a picture, regardless of where it is, our eyes will hunt for it. In the absence of such face, the picture as an overview, is a face.
Sounds like twilight zone isn’t it? well u heard it first here. Now keep shooting.
