Rule of Thirds

The rule of thirds is a rule which is used to aid the composition of photography, painting, and other visual arts. The rule states that an image can easily be split up into 9 equal sized sections via the use of two evenly spaced vertical lines, and two evenly spaced horizontal lines. 

When these lines are put onto an image it creates four points around the middle section of the picture. These are used to align features of the image, for example the trunk of a tree could be positioned on the right hand line of the two vertical ones. 

It has been said that using this technique creates a better composition and gives the picture more energy than simply positioning the main thing in the middle of the composition.

When using this technique the horizon line generally is in line with the top or bottom horizontal line and other parts of the landscape, for example trees are lined up with the two vertical lines. Doing this makes the image more aesthetically pleasing.
