Menu: Adjust -> Exposure

 

This tool can help you to fix images with incorrect Exposure.

 

For example, totally dark underexposed images can be restored to perfect exposure, of course, at a cost of raised noise. But this can be then fixed using Noise Removal tool. Unfortunately, too bright photos with clipped highlights cannot be fully restored. So it's always better to slightly underexpose the photos instead of overexposing them.
