Composition and the rule of thirds
Framing using the rule of thirds
Perhaps the most used and useful rule of composition is the rule of thirds. It is really very simple. If you imagine a frame with a line across both the horizontal and the vertical positions, one-third of the frame width in from each of the four edges of the frame, then any object placed on this line will have added importance in the overall picture. This division also produces nine identical boxes within the frame;later we will explore the importance of this.
