Retouch images and remove imperfections

Select the Spot healing brush tool   from the Retouch nested tools in the toolbar.

In the tool options bar, you can set your Brush size and Brush hardness. Choosing a brush size slightly larger than the area you want to fix ensures that you can cover the entire area with one brush stroke.

(Optional) Select Sample All Layers in the options bar to sample data from all visible layers. Deselect Sample All Layers to sample only from the active layer. 

Select the three-dots icon to access more tool settings. In the More options panel that opens, you can specify Spacing, Angle, and Roundness for your brush. You can also set your source sampling Type:

• Content-Aware: Compares nearby image content to seamlessly fill the selection, realistically maintaining key details such as shadows and object edges.
  
• Create Texture: Uses pixels in the selection to create a texture. If the texture doesn’t work, try dragging through the area again.
• Proximity Match: Uses pixels around the edge of the selection to find an area to use as a patch.

You can also toggle on/off Use pressure for size as required.

Click the area you want to fix, or click and drag to remove imperfections over a larger area in your image.
