The document discusses the rule of thirds in composition. The rule of thirds involves dividing an image into thirds both horizontally and vertically, creating nine equal sections. Placing subjects or key elements of a photo at the intersections of these lines can create a more balanced and appealing composition. The rule of thirds has a long history in art and is commonly used in photography, filmmaking, and other visual media because it follows conventions that audiences have come to expect. Examples are provided of tasks applying the rule of thirds to photo editing and storyboarding portrait shots for a newspaper.
