Tools and Their Functions
Clone and Pattern Stamp Tools

The clone stamp tool is a simple tool that has a limited but specific purpose.

Begin by creating a new document and drawing something on it using the brush tool - be creative! Be sure to leave a good bit of white space somewhere.

When you've finished, select the Clone Stamp tool on the toolbar.

Look at the options bar. Notice that the clone stamp tool's options are very similar to those of the brush tool. This is because they function in similar ways. Opacity and Flow affect the clone stamp tool in exactly the same way as the brush tool, as does the airbrush toggle. We already know how these function, so let's leave them at their default settings. Select a brush size for the clone stamp tool relative to the size of your drawing. A size of 21 should be suitable. After you've selected your brush, return to your image. Hold down the Alt/Option key and click once on your drawing, preferrably in the top left corner. After you've done this, move your cursor up into the white space and begin to paint with it.

As you can see, the clone stamp is used to make a direct copy of a portion of your image. Holding down Alt/Option and clicking defines the source for the brush strokes.

You can also use a variant of the clone stamp tool, called the pattern stamp tool. Instead of drawing strokes from a defined source point on your image, the pattern stamp tool draws preset patterns. Select the tool, then select a pattern on the options bar and draw on your image.

Such are the full capabilities of the clone/pattern stamp tools. Click continue to proceed to the effect tools - smudge, burn, etc.
