However, in some cases you will have already made changes on an adjustment layer, and you need to decide whether your cloning should include those adjustments. Photoshop lets you decide whether to include those changes in your cloning. After you have selected the Clone Stamp tool, the top row of your screen will include a circle with a line through it (see graphic above). Photoshop defaults to applying the changes of any adjustment layers, but if you click on this icon, Photoshop will ignore any adjustment layers when cloning.
