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.

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 usually know when I take the picture. There's always some kind of un-self-conscious thing going on, so that it doesn't look like they're there for the sake of having their portrait taken.

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.

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.

The idea of the portrait itself is my great love. The questions and answers in it can go on forever and ever. It is what happens in the eyes or with a tilt of the head. I keep going because it's too interesting to stop.
