This document discusses the principles of visual composition. It defines composition as the conscious selection and arrangement of visual elements using guiding principles to achieve a desired result. The three main elements of composition are emphasis, balance, and continuity. Balance refers to the equilibrium of opposing or interacting forces within a visual field. There are two categories of balance: formal symmetry, which involves equal distribution across an axis, and informal symmetry, which uses similar but not identical distribution. The document provides examples of different types of formal symmetries like true, virtual, radial, and crystallographic symmetry.
