The simplest shading type is constant. The colour of a constant shaded polygon’s interior pixels is always the same, regardless of the polygon’s orientation with respect to the viewer and light sources. Constant shading is useful for creating light sources, for example. With all other shading types, a polygon changes its shade as it moves.
Industry:Entertainment
Shot-to-shot picture fidelity. Improperly matched cameras may exhibit differences in level, balance, colorimetry, or defects that will cause the picture quality to change from shot to shot. These differences may present problems during editing, as the editor attempts to minimise differences.
