She clicked away with no motive besides recording the moment and keeping herself entertained. She had no plans to publish a book until her husband insisted a couple of years ago that she see if there was anything she might do with her mountain of images.

Don’t ask her for dirt. She can’t really tell you if the models were starving themselves, if they took drugs, if they threw diva tantrums.

“I just wasn’t looking for any of that. I have always just had a passion for making photographs of people, all kinds of people. My father used to say that you should look at everyone with equal eyes. I didn’t go backstage with any judgment.’’

The truth is, she didn’t know who most of the people around her were.

“I never recognize famous people. I was sitting once across from Kate Moss at a dinner. She was talking to this beautiful woman next to her and I turned to [fashion editor] Candy Pratts Price and asked who the beautiful woman was. Turned out it was Naomi Campbell. I had no idea.’’

Despite her lack of interest in becoming a fashion world insider, she made a fair share of friends — folks like designer Narciso Rodriguez, model Christy Turlington and Alber Elvaz, creative director for Lanvin. Her New York book launch on Feb. 19 at Barneys is being hosted by Rodriguez, Diane von Furstenberg and fashion writer Simon Doonan, all portrayed in Plus One.

“I can give you an example of how I got to know Alber Elvaz, who is such a genuine, smart, kind, dear man. I remember one day being backstage at one of his shows and in the middle of everything, he paused and walked over to a mirror. I didn’t know him that well then. But here he was taking a personal moment, looking at himself in the mirror. For a photojournalist, that would have been am amazing photo.

“But I didn’t take it. I didn’t need to. I didn’t have an editor demanding anything from me. And I didn’t want to steal the moment from him. But I knew that he knew that I saw that shot and that I chose to respect him.’’
