The Clone Brush tool is a fun and powerful way to edit your images by using parts of an image as a paint source. You can remove elements within your image by painting over them with another part of the image. The paint source can be part of the same layer, another layer in the image, a merged image, or a layer from another image.
To use the Clone Brush:
On the Tools toolbar, choose the Clone Brush tool .
On the Tool Options palette, choose the brush tip, size, opacity, and other options. See Setting Brush and Paint Options.
Mark the Aligned
mode check box to have the Clone Brush tool paint from the point
of the source area relative to the first point you clicked on the target
area each time you stop and start painting again. You can keep clicking
and dragging over the target area to fill in the source image.
Clear the check box to have every stroke copy the same data.
Mark the Sample merged check box to clone data from all layers merged together. Clear the check box to clone data from the current layer only.
On the source image, right-click or press Shift and click the center point of the source area.
Click and drag on the image you want to change to paint the cloned area.
