Birth photographer - advice please!

My husband and I are going back and forth on whether or not to have a birth photographer during L&D and after. We mostly want to have great photos of the three of us after our daughter is born- sort of that "first look" idea. Have any of you done this with previous babies? Are any of you planning to do it with this baby? I would love to hear advice on this topic. Specifically, if you did it, would you do it again- and was your experience positive?
