Light & Shadow in Drawing

Shading notes from the drawing side: how surface orientation, occlusion and cast shadows each produce a different kind of dark, and why confusing them flattens a drawing.

  1. 1Lighting #1 Surface OrientationThe first step in shading: before thinking about where the light comes from, sort every surface in the picture by which way it faces.February 21, 2021
  2. 2Lighting #2 Occlusion ShadowsThe second kind of dark: not unlit, but unreachable. How occlusion shadow behaves and how it differs from a cast shadow.March 7, 2021
  3. 3Lighting #3 ProjectionsThe third kind of dark: cast shadow. Constructing it for point and directional lights, and why it has to be drawn in perspective rather than guessed.March 21, 2021
