About this tool
Contrast stretches tones away from the midpoint: light areas get lighter and dark areas darker. A modest increase is what makes a flat photograph look crisp, and it is usually more effective than brightness for an image that simply looks dull.
Push it too far and the extremes clip — highlights turn to plain white and shadows to plain black, both losing detail permanently.
Common uses
- Making a flat photo look crisper.
- Rescuing a hazy or low-contrast scan.
- Softening a harshly contrasted image.
Frequently asked questions
- How much contrast is too much?
- Once highlights go pure white or shadows pure black, that detail is gone. Increase until it looks right, then back off slightly.
