Rule Of Thirds

 The rule states 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.  Proponents of this technique claim that aligning an image with these points creates more tension, energy and interest in the photo than simply centering the feature would.

The rule of thirds can be applied by lining up subjects with the guiding lines, placing the horizon on the top or bottom line instead of the center, or allowing linear features in the photograph to flow from section to section. In addition, many photographers recommend treating any "rule" of composition as more of a guideline, since pleasing photographs can often be made while ignoring one or more such rules.
