Two Ways to Remove the Background From a Photo - PC World
If you've ever tried "punching out" the subject from a photo, you'll find that Photoshop Elements' Magic Extractor makes it dramatically easier than using manual methods. To get started, just open a photo in Photoshop Elements. I'll use the photo on the left, which has fairly consistent background, ideal for removal. Choose Image, Magic Extractor from the menu.
The idea behind the Magic Extractor window is that you mark the subject you want to keep with the Foreground Brush tool and then mark the background that you want to discard with the Background Brush tool. Then the program will "magically" punch out your subject for you.
The Foreground Brush tool is automatically selected to begin with (it's on the left side of the screen). Use it to identify your subject. You don't need to completely fill in the subject; just dab some dots or lines around the interior.
It's important to mark regions that change color so the Magic Extractor knows they're still part of the main subject. If you need to, use the Zoom Tool (seventh from the top of the toolbar on the left) to get a closer look at your subject. Also, you'll want to make the brush smaller (using the brush size control on the right) to mark areas as needed.
When you're done highlighting the subject, click the Background Brush tool (second from the top on the left) and paint sections around the subject to mark out the parts of the photo you don't need, as you see on the right.
If you make a mistake, such as accidentally coloring "outside the lines," use the Point Eraser tool (third from the top on the left) to undo any marks.
When you think you've adequately marked your photo, click Preview (at the top right). You can continue painting with the Foreground and Background tools if needed, and make corrections with the eraser. When you're ready, click OK, and the subject will appear on its own, as you see on the left. From here, you can copy it into another photo or add a custom background.
