Alright, so I have photoshop CS, but that darn thing is so complicated. I see some portraits people do where they sharpen the eyes only, and they are BRILLIANT. How the eff do I do that?! Can someone give me some basic, step by step tutorial on how to sharpen the eyes? Aaaand any other basic techniques used to enhance portraits? I am trying to break in to portrait photography but need to master photoshop to acheive the results I truly want. Thanks guys!!
