It made my NYF WEEK when I got to exchange a few words with Bill Cunningham! I spotted him in the tent and scurried after him to get a shot, then tapped him on the arm and told him what a huge fan of his I was. He said,

"Are you having a good time shooting?"

I nodded vigorously and he smiled and said,

"Just keep on shooting."

Good advice. If you haven't seen it yet, the film.
