Rule of Thirds Composition
The Rule of Thirds is a guideline which applies to the process of composing visual images such as designs, films and photographs. The guideline proposes that an image should be 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, sometimes called power points1.
The Rule of Thirds is applied by aligning a subject with the guidelines and their intersection points (power points), placing the horizon on the top or bottom line, or allowing linear features in the image to flow from section to section.
Aligning a subject with these points creates more tension, energy and interest in the composition than simply centering the subject.
