Photoshop offers many intelligent tools to quickly fix image blemishes. One of those is the Spot Healing Brush tool. It gives you the ability to heal blemishes with a short brush stroke. It can quickly remove blemishes and imperfections in photos without the need of setting a sample point.
- Open a photo with a blemish (such as a skin tag, pimple, or sun spot.)
- Select the Spot Healing Brush tool in the Tools panel.
- Choose a soft-edged brush from the Options bar. Set the brush to be a little bit larger than the problem areas. The keyboard shortcuts of left and right bracket are useful to adjust brush size.
- Set the blending mode in the Options bar to Replace. This will preserve noise, grain, and hair texture along the edges of the stroke.
- Choose a Type of repair in the Options bar:
- Proximity Match. Pixels from the edge of the selection are used as a patch for the selected area.
- Create Texture. Pixels in the selection are used to create a texture to fix the damaged area.
- Content Aware. This option works best to automatically generate patterns based on the surrounding pixels. I usually try this one first.
- Click once on an area that you want to fix. You can also brush over a larger area. If you are unhappy with the spot healing stroke, simply undo and try again using a smaller brush. You can also try painting brush strokes in different directions to modify the results.
