I'm not usually able to photograph people, but when I saw this guy in the park, I just felt like I wanted to photograph him. The fact that he's a friend made it much easier. I asked him to take his glasses off, and the expression on his face as he looked at me... well, let's just say he made it really easy for me.
I don't usually print my images unless I think I can submit it in a show (to save paper). I also cropped in very tightly to capture the essence.
