Saturation Adjuster

Make dull holiday photos more vivid or calm down colours that look garish. The slider pushes each pixel's colour away from, or towards, its own grey value while keeping its brightness, so a positive setting adds punch and a negative setting fades the picture gradually to black and white.

Frequently Asked Questions

What is the difference between saturation and vibrance?

Saturation changes every colour by the same proportion. Vibrance, found in some photo editors, boosts muted colours more than already strong ones. This tool provides saturation.

Can I make a picture black and white with it?

Yes, −100% removes all colour using Rec. 709 luminance. The Image Grayscale tool offers more conversion methods.

Why do skin tones look orange?

Skin is sensitive to saturation. Keep the boost below about +30% for portraits.
