Extracting objects from their background (Photoshop)

The Extract command provides a sophisticated way to isolate a foreground object and erase its background on a layer. Even objects with wispy, intricate, or undefinable edges may be clipped from their backgrounds with a minimum of manual work.

Note: For simpler cases, you can instead use the background eraser tool.

To extract an object, you use tools in the Extract dialog box. First you draw a highlight that marks the edges of the object, and define the object's interior. Then you can preview the extraction and redo it or touch up the result as needed. When you extract the object, Photoshop erases its background to transparency. Pixels on the edge of the object lose their color components derived from the background, so they can blend with a new background without producing a color halo.

9 You can add back opacity to the background and create other effects by using the Edit > Fade command after an extraction. (See "Blending filter effects (Photoshop)" on page 322.)
