First if you need to do it quick then select background with magic wand, change the tolerance to try and get all the background but non of the main image, select invert which will put marching ants around the main image, now select modify and use contract/extract which will bring the ants in or out. Cut that out and place onto a new layer, right click the layer and mess about with the blending options.
or use the pen tool but its a tricky tool to use and could take a long time if your not use to using it. |
