Rule of thirds involves using a 9 by 9 grid placed over a photograph or piece of footage. This is used to help in the composition of the text, aligning features within it to make it much more visually pleasing. For example, the horizon is usually aligned with the lower horizontal line so the picture is divided equally. By lining up subjects with the lines of the grid, photos can be made to look much more professional.

In the image above, the subject, a wooden house, falls between the upper and lower lines of the grid. This means the subject is centered, drawing the eyes of the audience. The horizon also falls between these two lines, dividing the image equally.

When using the rule of thirds, certain things must be remembered. For example, when photographing a person, they are usually lined up with a vertical line. However, the rule of thirds is usually considered by photographers as more of 'guidelines' as unconventional photos can be taken not using the rule that can look aesthetically pleasing.
