The document discusses several rules and techniques of photography composition, including the rule of thirds, framing, leading lines, balancing elements, symmetry and patterns, and depth of field. The rule of thirds proposes dividing an image into nine equal parts and placing important elements along the lines or intersections. Framing focuses the viewer's attention by bringing the subject into view. Leading lines guide the eye through the photograph from foreground to background. Balancing elements distributes visual weight evenly. Symmetry and patterns create a strong focal point through mirrored repetition. Depth of field determines the distance between the nearest and furthest acceptably sharp objects in a scene.
