Principles of Design
Composition: the overall organization of an image
Balance: In symmetrical balance, either side of the image is equal in weight, and one side may reflect the other. In asymmetrical balance, the sides of the image are unequal.
Contrast: refers to a large difference between two things; for example, green and red, or light and shadow. This term refers to differences between those elements of art in a design. For example, a bright color in a painting will contrast with dull colors. Contrast is used to create tension and interest.
Emphasis: refers to a feature of a work of art that is highlighted or singled out. Elements of art are combined to focus attention on a single element of a composition.
Rhythm: repetition of line, light, shape, etc.
