Gamma Correction - Fix Image Gamma Online

What is Gamma Correction?

Gamma correction adjusts the midtone brightness levels in images to fix washed-out or dark photos without affecting pure black or pure white areas. This sophisticated image enhancement technique specifically targets the gamma curve to restore proper contrast and brightness balance. Perfect for correcting exposure issues, improving image visibility, and achieving professional-quality photo adjustments with precise control over midtone luminance.

Gamma Correction Applications

Fix washed-out photos from overexposure, correct dark images from underexposure, enhance visibility in difficult lighting conditions, restore proper contrast to faded photographs, improve screen capture quality, or prepare images for professional printing and display with accurate brightness representation.

How to Apply Gamma Correction

1. Upload your image for gamma correction
2. Move gamma slider to adjust midtone brightness
3. Preview gamma correction changes instantly
4. Fine-tune settings for optimal results
5. Download your professionally corrected image

Technical Gamma Processing

Gamma correction works by applying a non-linear transformation to the image's luminance values, specifically targeting the midtone range while preserving pure blacks and whites. This process uses the gamma curve formula where output = input^gamma, allowing precise control over brightness without affecting extreme values. Our tool provides real-time preview and maintains image quality while applying professional-grade corrections.

Professional Gamma Techniques

Use gamma values below 1.0 to brighten dark images, apply values above 1.0 to darken washed-out photos, combine gamma correction with other adjustments for comprehensive image enhancement, prepare images for different display devices with specific gamma requirements, or achieve professional photography results with precise brightness control.
