FAQ
Will brightness adjustment affect colors?
Brightness adjustment only changes photo brightness, not colors. If you need to adjust colors simultaneously, try saturation or color temperature tools.
Can I restore to the original image?
Yes. Click the "Reset" button to restore all settings to default values, or simply adjust brightness back to 0.
Does it support large image processing?
Yes. However, for optimal processing speed, it is recommended to keep image size under 10MB.
