The Healing tool is very similar, as it works a lot like a Clone tool that's set to a lower opacity. Because the Healing tool doesn't completely erase the object you're painting over, it's not as handy for erasing, but it can help you touch up your photos. Consider the photo to the left, in which my subject has hotspots on her face.

She would look better if we could take the shine off, and that's exactly what the Healing tool can do. Find the Spot Healing tool--it's in the cubby directly above the Clone tool. Now, just dab at the shiny bits you want to powder. The tool will automatically sample nearby skin textures to fix the photo.

If you don't like the results, you can use the more manual Healing Brush Tool, available in the same cubby. It works just like the Clone tool--you need to specify the source location first, and then you can paint.
