Frequently Asked Questions
What does gamma do?
Gamma adjusts the mid-tones without clipping the darkest and lightest areas, which helps brighten shadows or tame highlights more naturally than plain brightness.
Can I undo my changes?
Yes. Use the reset button to return every slider to its default and see the original image again.
Is my photo uploaded?
No. All adjustments run on the Canvas API in your browser, keeping your image private.
