Rule of third

Rule of Third

The rule of thirds is a "rule of thumb" or guideline which applies to the process of composing visual images.The guideline proposes that an image should be imagined as divided into nine equal parts by two equally-spaced horizontal lines and two equally-spaced vertical lines, and that important compositional elements should be placed along these lines or their intersections.

On the left is the orginal version and the right, the cropped version, the main differences are that the cropped version now has a horizontal line going through the horizon now and the Rock face now has two lines intersecting it whereas before it was dead in the middle looking quite boring.
