Using photographs of real people as examples causes readers to focus on the subject's facial features and age rather than the structure being explained. On this site, we use AI-generated images as educational diagrams specifically so that readers can focus on the structure itself.
The diagrams are not a guarantee of results. They are teaching tools for understanding how angle, shadow, gaze, and posture interact — not finished photographs to emulate.
Updated 2026-05-09: All 61 diagrams were replaced with educational illustrations matched to each article's content.
