Besides magazine portraits and news and feature stories a lot of my daily work consists of what might be called event photography. Typically my clients need a thorough photographic coverage, of an event that they are in charge of. It can be an in-house event like a conference or a large meeting but it can also be some kind of cultural event like a concert or festival.
In any case I approach these kinds of jobs just as I would any other news assignment. In my opinion there really isn't much of a difference. Besides the angle of approach perhaps.
In close corporation with the client, I try to find the essence of the event and what they want to communicate with the photos.
