About Image Gamma Correction Tool
The Image Gamma Correction Tool allows you to adjust the gamma value of an image. Gamma correction is a non-linear operation used to encode and decode luminance or tristimulus values in video or still image systems. Practically, it helps adjust how bright or dark the mid-tones of an image appear without significantly altering the pure black and white points.
How to Use?
- Upload your image.
- Use the slider to change the gamma value. Values below 1.0 darken the mid-tones, while values above 1.0 brighten them.
- Preview the result.
- Download the corrected image.
Features
- Non-Linear Adjustment: Targets mid-tones specifically.
- Precise Slider: Fine control over the gamma curve.
- Instant Feedback: See changes immediately.
- Browser Processing: Fast and secure local editing.
FAQ
What is Gamma in images?
Gamma defines the relationship between a pixel's numerical value and its actual luminance (brightness). It compensates for the way human vision and display screens perceive light.
When should I adjust gamma?
If your image looks too dark in the shadows but has correct highlights, or looks "washed out" in the mid-tones, adjusting gamma can often fix it better than simple brightness/contrast controls.
What is the standard gamma value?
Most computer displays and the sRGB color space use a gamma of approximately 2.2.
