My photo school can beat up your photo school!
All kidding aside, another B.A. (or B.S.) would probably be pretty pointless. I have a B.A. in music, and I went straight into an M.S. photo program. If you've got the portfolio, you'll get in no problem. That said, it might be worth trying to learn outside of a university setting. You can learn a whole heck of a lot assisting (check out
