About the Image Contrast Adjuster

The Contrast Adjuster expands or compresses RGB channel distance around the midpoint. It uses a standard bounded contrast factor and preserves alpha transparency.

How to use the Image Contrast Adjuster

Open the image.
Choose a positive value for stronger contrast or a negative value for flatter tones.
Apply and inspect detail at both extremes.

Practical tips

Small changes are usually more natural than maximum contrast.
Check faces and gradients for lost midtones before saving.
