Difference Between Healing and Spot Healing Brushes

The biggest difference between the Healing Brush and the Spot Healing Brush is that the Spot Healing Brush doesn’t require you to specify a sampling source. It automatically takes a sample from around the area to be retouched. The good news is that it’s quick and easy.
