Contrast Control

Boost contrast to make colors pop and add depth, or reduce it for a softer, flatter look. Works together with brightness for balanced adjustments.

Shadow & Highlight Recovery

Lift shadows to reveal detail in dark areas without blowing out bright spots. Pull back highlights to recover detail in overexposed skies and backgrounds.
