Cast Shadow: Are the dark areas that occur on an object or a surface
when a shape is placed between it and the light source.

Local Value: The relative dark and light of a surface seen in the
objective world, that is independent of any effect created by the degree of light
falling on it.
-
Tenebrism: A technique of painting that emphaisizes the effect of
chiaroscuro. Larger amounts of dark value are placed close to smaller areas of highly
contrasting light, which change suddenly, in order to concentrate attention on important
fetures.
-
Value Pattern: The arrangement or organization of values that control
compositional movement and create a unifying effect throughout a work of art.

The Difference between closed-value and open-value composition: In
closed value compositions, values are limited by the edges or boundaries of shapes but
in a open value comosition values can cross over shape bounderis into adjoining areas.
