In this lesson, we move from theory into application by painting one of the most essential exercises in art: the sphere. Through this simple form, you’ll explore how light behaves, how form turns, and how structure emerges from value relationships.

This is where the concepts of light family and shadow family become real. You’ll learn to separate them clearly, understand their roles, and organize your painting so that light and shadow never compete but work together to describe form with clarity and conviction.
