The document discusses 10 compositional theories of still photography: 1) Rule of Thirds, 2) Leading Lines, 3) Strong Diagonal, 4) Point of View, 5) Framing, 6) Simplify, 7) Depth of Field, 8) Strong Foreground, 9) Fill the Frame, and 10) Active Space. Each theory is defined and an example photo is provided to illustrate it. The document concludes that properly applying these compositional techniques can transform a ordinary snapshot into an extraordinary photograph.
