2. Change the size of the Clone tool in the Settings palette above the workspace. A large brush will reproduce too much of the image, while a small brush will be time-consuming and ineffective. Set the Hardness and Opacity to 50 percent, which will give you greater control and soften the brushstrokes.
3. The aim is to copy pixels from one section of an image to paint over nearby blemishes. Zoom into the area you want to correct, then place your brush next to the blemished area. Now either right-click or hold down Shift and click. This will select the undamaged area below your cursor as your pixel source.
4. Position your cursor over the blemish you wish to correct and click. This action will paint clean pixels on to the damaged area. Keep clicking until the area under your cursor is clean. Now position your cursor over any other blemished areas in the image and repeat as necessary.
5. You’ll notice that when you move your cursor your pixel source matches that movement. If you wish to keep it in the same place, ensure that Aligned mode in the Brush options palette isn’t ticked. However, you’ll get a far more natural result by changing your pixel source every few clicks.
6. The Clone Brush can also be used to paint strokes by holding down the mouse button as you move the cursor. However, this may create more problems than it corrects. I’d recommend sticking to the method outlined in steps 1 to 5. Remember to keep zooming out to see how your work is progressing.
