Overview
Linear encoding represents brightness proportionally to actual light intensity, while gamma encoding redistributes brightness values to better match human perception.
Why Gamma Exists
Human vision is more sensitive to differences in darker tones than brighter ones. Gamma encoding allocates more data precision to shadow regions where perception is strongest.
Workflow Differences
Linear space is preferred for rendering, compositing, and lighting calculations, while gamma space is optimized for display and storage efficiency.
Professional Insight
Understanding when to work in linear versus gamma space is critical for accurate compositing and grading.
