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.

I think people imitate actors - things they've seen in a movie or on TV, and before you know it, they're doing something with their face or their mouth. It's from some actor they think is cool. They might not even know they're doing it, which is kind of funny.

The conservatism is extraordinary to me; just compare the way they dress to the way their parents dress. There are still no tattoos or piercings, which is interesting to me. Why does everyone who lives in one place dress alike, look alike, eat the same thing, and decorate the same way?

I'm at the point now where I don't really have an agenda. I kind of let things flow, and there's not a narrative. On the set it's usually one or two people, and I'm not trying to choreograph them as I did in the past. I'm really just trying to see what's going on in their minds and in their faces.

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.

I sometimes get commissioned to photograph families, and they see the results and say, "Oh, I look terrible." And that's when I realize the difference between the people I choose and the people who choose me.

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.
