Light Logic Observing the way light interacts with an object or group of objects, noticing shadows and the resulting variations in value, is light logic. Think about how light falls on spheres, cylinders, cones, and organic volumes creating a gradual change from light to dark over their surfaces. Alternatively, cubes, pyramids, and other angular forms change abruptly from light to dark at the intersections of their planes. The intensity of shadows and how clean their edges are is directly related to the strength of the light and its proximity to an object. Light and shadow on a volume can be reduced to six categories, of course each subject requires more specific investigation to be accurate. The six categories are as follows: 1. Highlight (most often the brightest/lightest part of your object; where the light hits and bounces directly back) 2. Light (light is washing over the object, illuminating) 3. Shadow/Half Tone (true color of the object; the object is beginning to turn a...
