About this effect
Brightness changes the overall light level of the image in a straightforward way. It is the right tool when the photo feels too dark or too bright everywhere, not just in specific tonal regions.
Compared with exposure, brightness is simpler and more direct. If you only need a quick global light adjustment before exporting, this is usually the fastest option.
Best for
- Quick overall light correction

Common questions
FAQ
Can I both brighten and darken an image here?
Yes. The slider works in both directions so you can increase or decrease brightness depending on the image.
How is brightness different from exposure?
Brightness is a straightforward global light adjustment, while exposure usually feels more photographic and can preserve tonal relationships differently.
When should I use brightness instead of highlights or shadows?
Use brightness when the whole image feels off. Use highlights or shadows when the problem is concentrated mostly in bright or dark areas.
