In this tutorial I'll show you all how to use Photoshop's Spot Healing Brush to remove small unwanted objects from your photos, such as someone's hand in the corner of your photo or an individual in the background. This technique can also be used to remove unwanted facial features or fix spots someone's clothing.
This is a photo by Paul Stevenson that has a few pages in the background - I want to remove these pages. I'll open up the photo in Photoshop and select the Spot Healing Brush tool from the left (it looks like a band-aid).
The Spot Healing Brush is a powerful tool, but when we want to remove objects to make it as if they were never there, we'll want to use the content-aware mode of the tool. Select this mode from the top of your window.
At this point, using the tool is as simple as using the brush to brush over areas you want to disappear. Photoshop will delete those areas, and will intelligently gather information from the content around that area to fill in the blank area. This works best with a soft brush, so you don't get a sharp edge between the original content and the computer-generated content. This also works well if there's a pattern in the background, such as water, grass, or a fence.
