The rule of thirds:

1. an image can be divided into nine equal parts by two equally-spaced horizontal lines and two equally-spaced vertical lines. The four points formed by the intersections of these lines can be used to align features in the image. aligning a photograph with these points creates more tension, energy and interest in the photo than simply centering the feature would.
   

   This photograph of a sunset taken in the Thousand Islands region demonstrates the principles of the rule of thirds
