Gamma determines how midtones are represented between pure black and pure white. Different gamma curves affect contrast, brightness distribution, and perceived dynamic range. Standard gamma settings are designed for accurate viewing, while specialized curves such as log gamma prioritize detail preservation for post-production. Adjusting gamma influences how shadows roll off, how highlights behave, and how natural an image appears. Gamma must be managed consistently across capture, editing, and display to avoid unintended brightness shifts. Professionals rely on scopes and calibrated displays to evaluate gamma accurately.

Gamma curves shape tonal perception — they influence how light values are recorded and seen.
