im on CS5... so you have to select part of the image (magic wand) and then 3D on top menu and then Repousse ---> Current Selection.
from there you can mess around. im still playing around and learning haha.
if youve seen the other one I posted of the Knicks logo, I was seperating parts of the logo into its own layers, and that was the outcome... the 3dish popout look. still learning! haha
