When Choosing your wedding photographer make sure to review their portfolio to see if that is the style of photography that you like.
One photo does not determine ones style..
Lighting composition - do you like photos with flash? or without flash? Front Light or Backlight?
Framing - Do you like all straight pulled backed shots or tight, maybe slightly or extremely tilted?
Editing - Do you like Fully Saturated Colors or Lighter slightly Faded, Black & White, Sepia..etc
Also consider your photographer personality, does this person make you smile and be happy, or do they make you feel something else? You will be spending a lot of time with this person and he/she will be interacting with you family and friends.
I offer engagement sessions as a way to break the ice with my clients, and they get to know me and how I shoot, which also includes posing, working with the environment, background, available light, etc. So during the wedding, we already have some chemistry which allows for much better images and overall good feelings..
