During the ceremony I use two different camera bodies with a wide-angle and telephoto lens on each that I can quickly switch back and forth from (within just a few seconds). So for the processional, I might use my telephoto to capture the bride coming from further away from the end of the aisle and then swing to the groom for a close-up of his reaction as he sees her (hopefully capturing some tears or a big grin), then I might go to a wide-angle as she gets closer and then get behind as she passes by and zoom in to the groom's expression again between her and her father's shoulders. Then from there, I am moving around discretely during the ceremony to capture lots of different angles, and getting people's reactions and the key moments (some people have called me a 'ninja'). If you are choosing between adding a second photographer or an album to your package, I usually recommend getting an album because I am capable of handling everything on my own.
