# Shadows and Highlights

Balances tones.

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.
