When you're shy, a camera becomes an entry into life. It was a kind of shield I could hide my shyness behind, and it allowed me to become an active observer rather than a passive one.
Photographs help people look at things they may not be able or may not want to look at. Until you can look at something, you can't change it. First you have to look at it, then you have a chance to understand it and can change it.
The emphasis in doing any in-depth photography is on building relationships, quality relationships. It's what I call thirty-cups-of-coffee-a-frame photography. You need to enter into the community - not just photographically, but intellectually and emotionally.
