The still photographer on a movie set must be nearly invisible—stealthily alert to the moment that will distill time, like a sonogram of the movie taking shape. There are few virtuosos of the form.

Alfonso Avincola is one of them. A treasure of Italian cinema who is revered in America, Avincola is now 91 and living in Los Angeles. I invited him and his daughter, Federica Carrion, to Dan Tana’s, on Santa Monica Boulevard, last fall. He had never been, and Carrion said he was curious about the place. Wearing a leather jacket, he entered the crowded, noisy restaurant with a sure step. A shy man of delicate features, Avincola has a thatch of gray hair that hangs over his forehead, giving him an almost mischievous look.
