The various genres of photography are not in competition with each other, and in any case, if you wish to have a competition, I think there are really only two important kinds of photography in contention for the top spot: The first is medical photography, because it saves lives. In 2002, I had cancer, had a colonoscopy and had a certain kind of camera inserted up my backside which saved my life. Those were undoubtedly the most important pictures in the world to me.
The other important pictures are family albums. When someone’s house is on fire or they’re forced to flee their country, very often, the family album is the first thing they think to take. What they’re saying is that the most important thing in their lives are these pictures—they contain memory, love and the images of their loved ones.
