In drawing, the term value refers to the lightness or darkness that appears in the drawing. In essence, value represents the light and shadows you see in the natural world. When it comes to your drawings, you can use value to show the way light moves through a particular space and to create the illusion of three-dimensional form.

You can choose from two shading methods, depending on whether you want to build value by adding something to your drawing or by removing something from it. Coincidentally, these two methods are referred to as additive and subtractive drawing. In general, additive drawing works more efficiently when you’re creating a tightly rendered drawing, while subtractive drawing works better when you’re creating a more loosely rendered drawing.
