Light it convincingly from an invented light source

Set an invented light source and carry its effects consistently through a complete scene.

What it is

Combine form lighting, cast shadows, bounce light, and value structure without copying a reference. Choose the key light's position, strength, and direction, then apply that decision across every plane and object.

This integrates solid forms in perspective, clean light and shadow separation, local value and illumination, edge control, and material readability. Determine how each surface responds to the light setup.

Keep the lighting consistent across characters, props, and environment while preserving the scene's value structure and color scheme. The lighting should support the chosen story and composition.

You can check it when

• ✓Choose a light direction and type for a line drawing, such as a window, overhead lamp, or campfire, then render the scene without checking reference. The light should read across forms and remain consistent.
• ✓Check the finished scene in grayscale. The key light, cast shadows, and bounce light align across the major elements, with the value structure and composition intact.
