I was lunching one day at Pastis in New York when a woman got up from her seat and peered at the lamb stew that I was eating. She asked if it was good and I said that it was. I recognized her as Diane von Furstenberg and later I wrote to her to ask if I could photograph her. I remember we hardly spoke a word at the sitting. When I had set up, Ms. von Furstenberg arranged herself, I took the picture and she left.
