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 the frame into thirds and placing the subject at the intersection points. Framing uses something around the main subject to draw focus. Leading lines guide the eye through the photo from foreground to background. Balancing elements places the main subject off-center according to the rule of thirds while adding another object to balance empty space. Symmetry and patterns create strong focal points with mirror images but can become predictable without interest. Depth of field refers to the range of sharp focus versus blurriness in an image.
