Abstract
A lighting correction filter for selectively correcting lighting in computer animation is disclosed. The lighting correction filter can select a computer-generated object having one or more lighting attributes. The selected object can be a portion of an object, an entire object, a portion of a computer-generated scene, or an entire scene. The filter can then set lighting correction values for the lighting attributes of the selected object. The lighting correction values can be color values, exposure values, or both. The filter can apply the lighting correction values to the selected object's lighting attributes to effect a lighting correction in the object prior to rendering.
