Why Brightness?
Too dark? Too bright? Adjust the overall lightness of your image with a simple slider. This affects all pixels uniformly—great for fixing exposure issues or creating stylistic effects.
For more control, combine with contrast adjustment. Brightness changes the midpoint, contrast changes the range between light and dark.
Extreme adjustments can clip highlights (lose detail in bright areas) or shadows (lose detail in dark areas). Use moderate adjustments for best results.
Frequently Asked Questions
If you start losing detail in bright whites or dark shadows, you've gone too far. Watch for "clipping" where areas become pure white or black.
For simple needs, brightness works fine. Exposure adjustment (Pro feature) is more sophisticated and better preserves highlight/shadow detail.
