You can then modify it to suit your needs.

Say you have a picture of a camera body and you want to make an out
line of
that body. Is there a way to extract say a mm or mm and a bit of
the outside edge or do you just
trace around it with the pencil tool and clean up the edges with
transform or such.
I won't be around a computer with PS on it for a day or two, so i
