Rule Of Third

In the rule of thirds, photos are divided into thirds with two imaginary lines vertically and two lines horizontally makes three columns, three rows and nine sections in the images. Important compositional elements and leading lines are placed on or near the imaginary lines and where the lines intersect.

When taking a photograph with the rule of thirds in mind, it's always best to compose the photograph in the camera. This is so that you can avoid cropping later to retain as much of the image as possible and avoid reducing the quality of your photographs.
