Final answer:
Informal balance in an artwork is created when two sides of an image do not mirror each other, but still have approximately the same visual weight, amount of detail, shapes, or colors. This type of balance can be achieved by strategically placing elements in a composition to create a sense of equilibrium.
Step-by-step explanation:
Informal balance in an artwork is created when two sides of an image do not mirror each other, but still have approximately the same visual weight, amount of detail, shapes, or colors. This type of balance can be achieved by strategically placing elements in a composition to create a sense of equilibrium. For example, an artist may balance a larger, dark object on one side of the artwork with several smaller, lighter objects on the other side. By doing so, they create a sense of balance without relying on symmetry.
