There are two primary approaches to photography that are recognised today: Traditional and Photojournalistic. Traditional provides for more classically posed images and a great deal of photography control interaction on the day of the wedding. A photojournalist style of photography takes its cue from editorial reporting styles and focuses more on candid images with little photographer interaction. These are two extremes and many of today's photography will fall somewhere in the middle of these two styles.
A third style that is becoming more popular is a fashion-based approach. In contemporary/fashion-based photography, photojournalist will combine candid images of the events of the day with posed images that are inspired by editorial fashion photography as would be found in magazines like Vogue or Vanity Fair. This style often involves more innovative and dramatic post-processing of images.
