How to Extract in Photoshop
Adobe Photoshop is used by graphics artists worldwide to repair, modify, or create images used for a variety of media, from advertising brochures and magazine covers to television and movies. One of its most useful aspects is its ability to extract part of one image, and place it in new document by itself, or place it in another image entirely. CS2 has its own separate Extraction tool, but the technique used in this article will work in any version of Photoshop.

1
Open Photoshop. Go to "File." Click on "Open" and browse to the image you want to extract something from.

2
Go to the "Toolbar" and select the "Pen" tool. Click on the canvas at the edge of something you want to extract from the image. Now continue clicking along the edge of the thing you want to extract until to reach the point you started at. Click that first point again to close the shape. This creates a "path."

Open the Image you want to add the extracted selection to. Go to "Edit" and click "Paste." The extract selection is now in on its own layer. Use the "Move" tool to move it where you want it in the image. Then go to "Edit" and "Transform." Click on "Scale" and adjust the size using the handles. If your were putting this in a blank document, you are finished. If you were adding it to a photo with other people or objects, go on to step 5.

Go to the Layers Panel and change the "Opacity" of the top layer to 50 percent or so. Make sure the object you pasted in is positioned where you want it. Then use the "Polygonal Selection" tool to select any areas of the pasted in layer that would not be seen if the object were really in the image. For instance, if you are pasting in a head so it looks like the person is standing behind other people, select those parts of the head or body that would be hidden by other people or objects. Then click "Delete."
