The basic philosophy behind the rule of third is to avoid a symmetric compositon which is usually pretty boring because the view is centered. To counteract symmetry the "Rule of the Thirds" can follow two concepts:
1. The rule of thirds that most photographers will tend to think of is the viewfinder grid division into nine sections, as seen here. So we can divide the image into two distinctive areas which cover 1:3 and 2:3 of the size of the picture.
2. The central four points of the middle rectangle - outlined in red - represent the key points of the composition and it is at one of these four points that you would place an important subject matter.
This concept of the rule of thirds is so accepted that some companies are offering cameras with auto focus points at the important grid sections as above.
