The spot healing brush made its debut in Photoshop Elements 3, but now an enhanced version of it is available in Photoshop CS2. The spot healing tool is different from the existing patch and healing tools in that it does not require you to make a selection or define a source point before using it. As you can see in the screen shot above, Photoshop CS2′s spot healing tool has more options than the version in Photoshop Elements 3. You can select a blending mode for the healing, and choose between proximity match or create texture. You can also sample all layers which allows you to use the spot healing tool on a new layer for non-destructive editing.
With the spot healing tool, you simply click on or drag across the flaw you want to remove and it disappears. The retouched area is blended into the surroundings seamlessly — most of the time anyway. It takes a little practice getting a feel for how brush size and healing work together, but most of the time it does an impressive job.
