Features: Under natural light conditions, the light source is complex and varied, making the relationship between light and shadow on objects intricate and subtle, even "fragmented" and "scattered." As a result, it becomes difficult to grasp the form. This requires the artist to have a strong sense of form and to understand light and shadow based on the fundamental shapes of the subject. This book includes the step-by-step process for drawing plaster portraits under natural light conditions.
