One of the best things about the total deal I got on my Mamiya 645Pro was the polaroid back that was included. I figured at some point I’d buy some polaroid film and try it out, but it wasn’t until I moved to Seattle and discovered Rare Medium (a store/gallery that specializes in all things polaroid) that I actually took the plunge. Granted, the Polaroid back means my Mamiya is bulkier than usual and thus not as easy to carry around, but I love the results so far. Peeling back the polaroid film is almost as cool as seeing an image appear in a developer bath.
