This document discusses concepts of camera composition including symmetry, asymmetry, the rule of thirds, depth of field, and foreground/background. It explains that composition is the arrangement and structure within the frame and separates it into those key sections. Symmetry involves balanced sides while asymmetry is unbalanced. The rule of thirds involves placing subjects along an imaginary 3x3 grid for balance. Depth of field refers to what is in or out of focus, and foreground/background considers subject placement near or far from the camera.
