SHADOWS AND HIGHLIGHTS
Shadows and highlights add depth, texture, and visual interest to a painting. Make sure to carefully observe objects, their shadows, and their highlights. Consistent shadows and highlights will add credibility to your work. Notice that the closer an object is to a wall or surface on which its shadow falls, the more defined its shadow will be. Highlights also vary depending on the lighting and surface of objects. Use shadows and highlights to capture textures and dramatic contrasts.
