Composition and angles.

 Here is a very famous scene from Star Wars, A New Hope.  It shows Luke Skywalker looking at the beautiful binary sunset.  In this scene George Lucas used the rule of thirds to make this scene look more appealing to the audience as he is looking at the binary sunset so he is more to the side of the shot.  Here is an example from the scene with the grid for the rule.

See how he is on the left line and therefor makes the image more appealing than for example this shot that I edited:

This shot is not as appealing as the shot before as he has barely any space and it doesn’t show that much if he’s looking at something bigger than him.
