Moving the slider on the scroll bar to the right (10.0) increases the brightness. Moving it to the left (0.1) decreases the brightness. The default setting is 1.5.

### Level/Curve The Curve command is another way to make precise adjustments in the highlight, midtones, or shadow levels in your images. It will correct the gray/color values in an image by altering the curve that represents the brightness values of pixels. Click Reset to cancel the changes and return the value to the default setting.
