More on reportage and weddings
Reportage is different from traditional wedding photography, which is for the most part concerned with controlled or staged portraits. Reportage is more concerned with capturing the story of an event as per a photo essay. Trying to capture the spirit and character of the guests. The traditional way to achieve this was to stay in the backgroung photographing candid shots as you see events unfolding. It is true there are reaction shots which are natural. It is also possible to interact with guests to create shots and still their reactions are natural and show their true emotions at that moment.
