This document discusses 10 rules of image composition in photography: 1) The rule of thirds, which positions important elements along imaginary dividing lines; 2) Balancing elements by including secondary objects to fill space; 3) Using leading lines to guide the eye through the scene; 4) Incorporating symmetry and patterns to attract attention; 5) Considering viewpoint and angle; 6) Managing the background to avoid distraction; 7) Conveying depth through foreground, middle ground and background; 8) Framing with natural borders; 9) Cropping to focus on the main subject; and 10) Experimenting freely in the digital age.
