Paint Edit > Color correction > Brightness & contrast

Use the Brightness and Contrast window to easily adjust the appearance of an image layer. Please note that these changes happen only on the current layer.

Choose an Adjustment Type. The Adjustment type determines which range of color values will be modified. You may choose to modify:

All color tones
Only highlight
Only midtones
Only shadows

Adjust the Brightness Factor and Contrast Factor sliders to update the image on the bottom left, for comparison with the original image at the top. The slider values can be negative. The defaults are 0.0.

The smaller the values (both positive and negative), the finer the adjustment.
