The Three-Point Lighting System

Every professional photographer and cinematographer relies on the three-point lighting setup. Here's how to implement it in GLM-Image:

1. Key Light (主光源)

The key light is your primary light source, creating the main shadows and defining the subject's form.

Fill light softens the shadows created by the key light, revealing details without eliminating depth.
