Balance in art and design refers to the way in which elements of a piece are arranged in relation to each. Balance can either symmetrical or asymmetrical. Below are example of each and descriptions regarding the effects of either kind of balance.
This images are prime examples of asymmetrical balance. Asymmetrical balance is defined as the uneven placement of objects within a piece that still work harmoniously with each other. Typically, as is seen in this photo above, a large object is complimented by multiple smaller objects. Another technique frequently used, and displayed in the photo below, is to place the larger object closer to the center and the smaller objects further away. The use of asymmetrical balance is especially useful for capturing the observer's eyes.
These next two images exhibit symmetrical balance. In symmetrical balance objects within the image are given equal weight, or emphasis. In other words, a line of symmetry can be drawn either horizontally, vertically, or diagonally and either side of the line are mirror images of each other. Many people are drawn to symmetry as it found commonly in nature. Both images shown display vertical symmetry, meaning that line of symmetry can only be drawn vertically.
