The Extract Command

The Extract command in Photoshop enables you to isolate a foreground object from its background. Even objects with undefinable edges like hair can now be clipped from their backgrounds with very little manual work. Open the image with the object you want to isolate. I choose an image with a pigeon to demonstrate better that you can extract it with a high level of precision

After you have loaded an image, go to Image>Extract. You'll see the same image come up in the Extract window.

The first thing we'll need to do is outline our foreground object, in this case it will be the pigeon. Select the Edge Highlighter tool (as shown). Now set a brush size and outline your foreground object. Zoom in if needed

Now we need to fill our foreground object by using the Fill Tool. Select this tool and click in the center of the object.

Now we are ready to preview the image by pressing the "Preview" button at the top right corner of the window. You now should see the background disappear. Under the Preview Options you can change the background color if needed. If you like what you see, then press the OK button.
