Clone stamp tool not pasting cloned area
Hi, I am trying to work the clone stamp tool and its not working. I hold option and click on the area I want to clone, then drag my trackpad over where I want the cloned area and it doesn't do anything. I am cloning the background layer and have the clone option as current layer. All settings are as standard and when I have cloned I can see the preview but when I then drag onto the part I want to paste that, it just doesn't do it.
Any help is appreciated.
