# Shadows and Highlights

This tool lets you make adjustments to the darker areas (shadows) and brighter areas (highlights) separately. Shadows can be made brighter and highlights can be made darker.

**Shadows**\
Sets the strength of the shadow adjustment. Higher values increase the brightness in dark areas, making it easier to see details in the shadows.

**Shadow Tonal Range**\
This sets which pixels are considered to be shadows. Lower values will limit the effect to very dark pixels only. Higher values include lighter pixels as well.

**Highlights**\
Sets the strength of the highlight adjustment. Higher values decrease the brightness in bright areas.

**Highlights Tonal Range**\
This sets which pixels are considered to be highlights. Lower values will limit the effect to very bright pixels only. Higher values will include darker pixels as well.

**Halo reduction**\
In some cases, halos may become visible around sharp edges. In this case setting this adjustment to a higher value may reduce the halos.

**Saturation**\
A convenience function that sets the color saturation after the shadows and highlights have been adjusted.
