The Patch Tool is one of the most useful tools in Adobe Photoshop and it is part of the healing brush set of tools. All these tools are geared towards retouching and repairing images, but there are certain differences among them that you need to understand.
The Patch Tool can repair even larger areas of an image, unlike the Spot Healing Brush Tool. It can also help you eliminate various distractions and blemishes.
How The Patch Tool Works
This tool can repair a selected area with pixels from another area or a pattern (even though it’s not really common to use patterns). Just like the Healing Brush Tool, the Patch Tool can match the texture and lighting of the sampled pixels to the source pixels. In addition to this, the Patch Tool can be also used to clone isolated areas of an image.
Simply speaking, you can use the Patch Tool to select the part of your photo you want to get rid of or duplicate certain areas of your photo. The great thing about this tool is the fact that it will take care of the edges of your selection automatically. A slight feathering that the Patch Tool provides will almost make it look seamless as you replace the selected part of the photo.
Of course, you have to make sure that your new selection is an area that’s similar to the area you are trying to patch. This tool, no matter how advanced it is, cannot bridge really strong differences in texture, lighting, and shading.
Differences Between The Patch Tool And Healing Brushes
While the Patch Tool is quite similar to the Healing Brush Tool, it functions in a different way. It matches the texture, lighting, and shading of the sampled pixels to the source area by using selection-defined areas instead of a brush. In that sense, it’s similar to the Clone Stamp Tool.
Before Photoshop CS6, it wasn’t possible to work on a separate empty layer when using the Patch Tool – it was necessary to duplicate the current layer. However, in Photoshop CS6, the content-aware option was introduced to the Patch Tool and now it’s possible to work on an image using an empty layer as well!
In the following brief tutorial, we’ll explain step by step how to use the Patch Tool. This will work for any version of Photoshop starting from CS6.
Repairing An Area With Sampled Pixels
1. Open the image you want to fix.
2. Select the Patch Tool.
3. Do the following – select the area you want to repair and select Source in the options bar or select the area from which you want to sample and select Destination in the options bar.
4. If you’re not satisfied with your selection, you can adjust it – shift-drag to add to the existing selection, Alt-drag (Windows) or Option-drag (Mac OS) to subtract from the existing selection.
5. In order to use texture with a transparent background from the sampled area, you should select Transparent. However, you don’t need to select this option if you want to fully replace the target area with the sampled area.
6. You should adjust the Diffusion Slider in order to control how quickly the pasted region adapts to its surroundings. Lower values are great for images with many fine details while higher values are adequate for smooth images.
7. Finally, you should position the pointer inside the selection and drag the selection border to the area from which you want to sample.
8. When you release the mouse button, the originally selected area is patched with the sampled pixels. Alternatively, you can drag the selection border to the area you want to patch. When you release the mouse button, the newly selected area is patched with the sampled pixels.
