Photographer Peter Simon found himself in the frame Tuesday at the opening of an exhibit of his work at the John Varvatos boutique at Copley Place. Over the course of his 50-year career, Simon, who lives on Martha’s Vineyard, has turned his camera on everyone from rock ’n’ roll frontmen Mick Jagger and Robert Plant to reggae icon Bob Marley and Robert F. Kennedy. His work is chronicled in a new DVD, “Through the Lens: Celebrating 50 Years of Personalized Photojournalism.” (The show of Simon’s iconic images will also travel to Varvatos’s stores in San Francisco, Los Angeles, and New York.) Told Tuesday that he looked sharper than usual, Simon confessed he was styled for the occasion by a Varvatos staffer. “My son says this sweater costs $1,000,” he said. Among those admiring Simon’s work on the wall were his wife, artist Ronni Simon, son Willie, niece Sally Taylor — the talented daughter of singers Carly Simon and James Taylor — General Catalyst Partners cofounder David Fialkow, malpractice attorney Alex MacDonald, fertility specialist Dr. Merle Berger, and Lou Reed’s longtime drummer Tony “Thunder” Smith.
