The traditional way of creating a pleasing composition for a well-balanced picture, the Rule of Thirds has been used in fine arts for centuries. Photographers have adopted it as well, as an alternative to composing with the subject centered with a "bull's eye" approach. Actually a principle of visual design and not a rule per se, it recommends placing the subject, or the most important line in the scene, at one of the recommended locations within the image area.
The landscape photo illustrates a Rule of Thirds composition with the most important subject area, the person's head, placed at or near one of the points where the imaginary grid lines intersect. When a scene includes an obvious line, as in the sunset image, place that approximately along one of the imaginary grid lines. (c) 2010 Peter K. Burian
Imagine that your camera’s viewing screen (or the LCD in Live View) is etched with grid lines like a tic-tac-toe game. When composing a scene, position the most important small subject at or near one of the four points where the lines would meet. Whether the most important small subject is a distant pyramid, a red shed in a farm landscape or a bright green apple on a tree, place it at one of the intersecting points. And if there's a horizon or other line, compose so that it's positioned at or near one of the grid lines.
Note: Some digital cameras allow you to select a function that projects a grid pattern over the image but the grid is rarely designed for the Rule of Thirds. Some newer cameras do provide two or more options for the type of grid pattern and that often does include one that works well for the Rule of Thirds.
Here are some additional suggestions about applying this guideline for effective composition:
- When you want to emphasize a dramatic sky, place the horizon along the lower line in your imaginary grid. If the sky is dull, but still important to the story of the photo, place it along the higher line.
- In a wide-angle photo with a small primary (off-center) subject, there may be too much empty space in the frame around it. If all of that “negative space” is distracting, try to include another smaller or more distant object that relates to the subject, such as a colourful bush in a landscape photo.
- Sometimes, the subject will be quite large in the frame, as in a portrait of a person or an animal. In that case, place the most important small element, such as the closest eye in a portrait, at one of the intersecting points.
Before you do so, however, it’s worth knowing and practicing the proven guideline. After it becomes second nature, begin to experiment by breaking the so-called rule. But do so knowingly and intentionally.
Finally, show only your most successful images to others and you will develop a reputation as a photographer with a “good eye”.
