VALUE (LUMINOUSITY)

Value dominates our visual experience. It is the strongest element of visual contrast and largely determines our perception of form as we explore a picture. It defines our perception of space through the luminance differences between the lighted and dark surfaces of three dimensional objects and long distance effects of aerial perspective.




Value also refers to:

-relative degrees of luminosity—that is, the presence or absence of light
-the working with shadows to imply light.
