Step 2
Now let’s add a photo: buy the image from Shutterstock at tinyurl.com/l3netx, or use a similar photo of your own. Then use the Pen tool (P) to create a path to extract the man from the background. Convert the path to a selection by holding Cmd/Ctrl and clicking on the thumbnail of the path.

Step 3
Duplicate the image onto a new layer and use a big, soft brush to erase part of the arm, painting over the mask. Name this new layer ‘model arm’, and the initial layer ‘model’.

Step 4
Duplicate the ‘model arm’ layer and go to Filter > Others > High Pass. Set the radius to 10 pixels, and the blending mode to Hard Light.
