The document discusses several rules and techniques of photography including the rule of thirds, framing, leading lines, balancing elements, symmetry and patterns, and depth of field. The rule of thirds involves dividing an image into thirds both vertically and horizontally to place important elements. Framing focuses the viewer's attention using doorways or archways. Leading lines guide the eye through an image along paths or edges. Balancing elements evenly distributes weight across the image. Symmetry and patterns create reflected repetition. Depth of field determines the range of sharp focus that depends on camera settings and viewing size.
