People aren't really looking at the result when taking a picture on an iPhone. And they don't print it. So to me, it's almost not a photograph. It's like looking in the mirror. It's a tool I don't relate to at all.

I feel as if most people are pretty much the same within a certain class, due to the schools they attend and the way they are raised.

Shooting great-grandchildren of some of the people I had photographed in the past, who are around the age of 15, is fascinating to me, because they're right on this fine line between still being children and starting to become themselves.

Can you see the deaths, divorces, job losses or changes, disappointments, surprises, and successes on people's faces? Have they been happy, sad, disillusioned, or gratified? I have been trying the single, vertically shot portrait with my 8 x 10 since 1985 and never felt I succeeded in finding what I was looking for.

My theory is, the more pictures you take, the better you get. It's like a sport. I never wait to get a particular shot because wonderful accidents can happen when you shoot a lot.

I never thought that my work was going to become well-known. It started happening slowly, without my realizing it. But when I did, it was terrifying. I still can't believe that people let me photograph them. The trust is amazing. But I've always put them in a context that is dignified, and that's really important.

I know now that before I take a picture I have to be sure about how I feel about the subjects. What I don't know is if I should explain to them what I'm doing while I'm photographing them.
