I've been working as a freelance photographer for about 8 years now. In the beginning of my career, I specialized mostly in Politics and General News. Eventually I developed into an all around photographer, shooting war scenery as well as the Berlin Love Parade.
I found that it doesn't matter who or what you take photos of, as long as you are aware of your profession: The permanent struggle for truth and truthfulness. For me, a camera is a tool, just like a writer's pencil. Photography, in the end, is nothing but the proper combination of exposure time and F-stop. Everything else in a photo, is subject to the viewer's imagination. A photographer cannot gain control over it, and a photojournalist shouldn't even try. Should I ever lose that conviction, then hopefully I will have the courage to quit.
