Quick Tips
Start Small
Begin with +20 or -20 and adjust from there. Small contrast changes often make a big visual difference.
Watch the Extremes
Check the darkest and lightest parts of your image. If they turn pure black or white, you've gone too far.
Combine with Brightness
After adjusting contrast, the overall brightness may shift. Use our Adjust Brightness tool to fine-tune.
