One more thought to consider is the photographers area of expertise, excitement, and creativity. When looking at a portfolio, a client should be able to see where the "favorite" style of photos lie. The reason why this is important is that your session will be more fun, and the finished photos will be more than expected. Most photographers have a favorite style of photos to shoot as well as a knack for certain subject matters. However, if your personality meshes well with the photographer and the photographer shows great professionalism, most of the time the photo session type won't matter.
