About this effect
Gamma changes the brightness of midtones more than a simple all-over adjustment. That makes it useful when the image needs tonal correction but you do not want the whole edit to feel as blunt as brightness.
If brightness or exposure feels too broad, gamma can be a better refinement step. It is especially useful when the middle of the image feels dull while shadows and highlights are already close to acceptable.
Best for
- Midtone correction

Common questions
FAQ
What does gamma do to an image?
Gamma shifts midtone brightness more selectively than a simple global light adjustment, which can help rebalance the image more gently.
Is gamma useful after exposure adjustment?
Yes. Many edits use exposure first for global correction and gamma after that to fine-tune midtones.
When is gamma better than brightness?
Gamma is usually better when highlights and shadows are close to acceptable but the middle tonal range still feels off.
