Lighten the image without an opaque AI promise

The preset starts at brightness +20 and leaves the controls editable. Use exposure for a broader change or shadows and highlights for more targeted tonal balance.

The editor does not reconstruct clipped highlights, relight a scene, create HDR detail, or analyze the photograph with AI.

Frequently asked questions

Does this automatically analyze the photo?

No. It starts with a fixed brightness adjustment that you can change.
