An artist might use equalization to allow the eye to move freely across the piece and/or to communicate the equal importance of all of the subjects/shapes in a painting. This lack of hierarchy can convey an attitude of inclusivity and motivate the viewer to identify with many characters that are given equal respect and attention. Non-representational works that equalize focus might use an overall abstract pattern that fills the piece.
