I was intending to shoot a wedding this weekend, being very new at this, I'll tell you my plan, then subscribe to the thread to get some advice from others as well.
I want to make an iPhoto book for a friend of mine, I was going to set the camera (Nikon N65) in program modes (portrait and auto, mainly, I suppose) to take the majority of pics, until I learn a lot more. About the only thing I was going to do any different was to add a diffusion filter to the bride's pic, and win the rest, making a sort of story out of the procession with the book.
