Basic Photoshop Tutorial - Spot Healing Brush Tool

The Spot Healing Brush is primarily used to quickly remove blemishes, imperfections or other unwanted elements from an image. To use it, paint over an imperfection you’d like to get rid of using a suitable brush (brushes can be selected and modified in the options bar). The Spot Healing Brush Tool will automatically try to repair the imperfection by sampling the surrounding area.

Careful! Although the Spot Healing brush can be a great tool for quick fixes, it’s not always guaranteed to work if the area surrounding the imperfection is busy. Generally speaking, the surrounding area should be an approximate match in color & texture to what you want to take place of the unwanted element in your image.

Healing Brush Tool

The Healing Brush Tool performs a similar function to the spot healing brush tool mentioned above. Instead of automatically trying to determine the lighting, shading, and texture from the surrounding area, the healing brush tool lets you manually select a source, and then paint over an imperfection. To select a source, hold alt and click the desired part of the image. Then paint over the area you wish to replace. As with the Spot Healing Brush Tool, settings such as brush size can be controlled in the options bar.
