The rule of thirds is a technique that recommends placing the focal point of an image near the intersection of imaginary lines that divide the image into thirds horizontally and vertically. This helps draw the viewer's eye to the most important part of the image. Examples demonstrate using the top right area to feature a parrot and the central area to highlight flowers. Following the rule of thirds can help make the most eye-catching parts of an image, like a magazine cover, really stand out.
