Clone Stamp Tool

The Clone Stamp Tool paints with a sampled pixels of an image.

1. Open an image to your choice.
2. From the Toolbox, choose the Clone Stamp Tool.
3. In the Options bar, set the tool's tip size and hardness as we did it for the Brush Tool.
4. Point the cursor at the image area you want to paint with, hold down [Alt] key, then mouse-click. You have just selected the source point for cloning.
5. Paint with the copied pixels.
6. The "Aligned" gadget in the Options bar (checked by default) forces the source point to follow your mouse, even after you complete a stroke. In other words, every new stroke continues the image started by the first stroke.
7. Deselecting the "Aligned" option starts the sample point back to its original location every time you release the mouse button. That is, every new stroke re-starts cloning your image from the source point.

Tip. Just in case you didn't know, the Clone Stamp tool is also available in Photoshop Elements that is way cheaper version.
