The "technical beam" in the eyes can help. But how genuine is it. It can be overdone if you decide to use a modifier indoors or out with the silver side. Then your subject may look like he or she is from another planet.
Just decided to use this shot from my cousin's graduation to illustrate this. If you see"catch light" tell me. So I could go to my "eye company" and demand my money back.I must apologize for the technical flaws-like the not so smooth background-it was a spot provided by the authorities or maybe I just chose to use the area,can't remember. Also, I am not a Photoshop user- not whining, indicating my limitations.
Or if you wish, drop me a line or two.
