ABSTRACT
This chapter covers the essentials of the subject of light and shade through a series of illustrations. The information presented here is very important to the rendering of realistic folds in all their beauty, subtlety and three-dimensionality. The chapter covers the most important elements of light and shade. In order to be seen, objects must be illuminated by one or more light sources. The light that hits an object is reflected in many directions, and some of it reaches the observer's eyes. When shading a drawing is done from the imagination, every angle of every surface has to be considered to judge how much light would reach that area, and how much would be reflected to the observer's eyes. The 20 figures that follow illustrate the most important concepts of light and shade in drawing and painting. The best way to light an imaginary scene convincingly is to apply these principles very consistently when shading one's drawing.
