This tool offers three different modes for retouching away photo defects: the Healing Brush 
, the Clone Stamp 
, and Structure Cloning 
. Clone Stamp transfers everything at the source region to the target region, while the Structure Cloning and Healing Brush modes only transfer the source’s structure – although the Healing Brush also unifies the background at the target. To set the source region, hold down the [Ctrl] key and click. To let the program choose a source region automatically, use the Seek source region automatically option. With normal settings, each left-click starts a new brush stroke 
; to change this, switch into Add Brush Stroke 
or Remove Brush Stroke 
mode. To turn these modes on temporarily, use [Shift] or [Alt]. The brush parameters can be forced to be the same in both modes, or allowed to be different – to change this, use Shared Brush Settings 
.
After choosing a mask, use the slider here to set its intensity in the range from 0 to 100 percent.
