Rule of thirds.

The rule of thirds:

The rule of thirds is applied by aligning a subject with the guide lines and their intersection points, placing the horizon on the top or bottom line, or allowing linear features in the image to flow from section to section.  The image is split up into 9 boxes which shows where the subject is placed in an image. It can be used both portrait and landscape. It’s been proved that the human eye doesn’t actually look at the centre of an image when its looked at. This means that the subject does always have to be in the centre of the image due to the human eye not automatically been focused to the main subject.
