The best way to illustrate one of the most popular photography composition techniques, the rule of thirds, is to put a nine-square grid over a photo. You would break an image into thirds both horizontally and vertically, arriving at nine segments total. If you place the most interesting element of your photos along one of those lines, your photo will naturally be well-composed, based on the general rules of form photography.
Balancing Elements
Placing your main subject off-centre, as with the rule of thirds, creates a more interesting photo, but it can leave a void in the scene which can make it feel empty. You can achieve a balanced composition and even out the main subject’s “visual weight” by including another object of lesser importance to fill the space.
