Photographer/bridesmaid

This is going to be weird, but keep an open mind. My VERY Best friend is an amazing photographer. She refuses to let me hire someone and I refuse to NOT let her be my bridesmaid (HA). I've agreed to let her take whatever pictures she wants but how can she take the ceremony pictures? We've come up with a couple ideas but I wonder if they are just tacky. Her husband takes pretty good pictures too and I told her to let him take the ceremony pictures. She wants to walk down the aisle and then wrap around and take pictures. She will do whatever I ask, obviously because she's a great friend but would that be really tacky? Haha.
