To get to the healing brush, click the little bandage icon in your tool box. Or you can access it via shortcut by pressing the "J" key on your keyboard. When you click and hold down on this bandage, you will see some different healing brush tool options: Spot Healing Brush Tool, Healing Brush Tool, and Patch Tool. Well, what exactly do these tools do and how do you apply them?
- Spot Healing Brush: This is the simplest tool of the three options and is used on small imperfections where there is an even area to sample around the blemish. This tool actually takes a sample from the pixels around the blemish and matches it in the lighting, texture, and tone. After selecting this tool, choose a brush size that is slightly larger than the blemish and just click on the blemish. For slightly larger marks and scratches, the brush may be dragged across the area. The blemish should be gone! Presto! For areas with fine detail, you might want to consider the next tool.
- Healing Brush: The healing brush allows you to select your own sample (known as the source) or a preset pattern to blend the imperfection with the rest of the image. Say you have an image where there is very fine detail in the imperfection. Select the healing brush tool and alt+click (option+click for mac) to select your source sample. When selecting the source, you are looking for a part of the image that closely matches what you would like the blemished area to look like afterward. Consider tone, texture, and highlights/shadows when selecting the source. After choosing your source sample, click on the blemish as you would with the spot healing brush to blend the imperfection. It may take some trial and error plus sampling from multiple parts of the image find the perfect blend to the imperfection.
