There's never a time that I'm not intrusive. That's the base of what we - photographers - do: we're intrusive. Anyone saying the opposite is silly. There's a process and a means of getting to know people and getting them to trust you, but I'm always very aware that I'm visiting - that I'm there, that I have a responsibility, but I am intrusive.

Approaching people is not - it's ironic that it's what I do - but it's not necessarily what I enjoy doing. Later on, I'm fine. Once we get talking I have a great time but not in the beginning.

My biggest problem is I'm so uninteresting that all these people forget I'm around.

I'm often uncomfortable taking pictures, especially if people are grieving, or hurt, or hungry. At such times I have to remind myself that I'm a photographer and that this is my job.

I can photograph someone if I can touch them.

That's one of the troubles of photography; the implication that what you have in that photograph is the way it is, and of course a year later that's not the way it is. Life moves on and the picture stays. That can be a wonderful idea to be a part of history and on the other hand, you think pictures have a life that they don't have.
