When She & Him asked fans not to take photos at their concert at the Bank of America Pavilion this week, he and she were serious. “At the request of Matt & Zooey, we ask that people not use their cellphones to take pictures and video,” read a flier posted at the venue, “but instead enjoy the show they have put together in 3D.” (There also was an announcement over the PA.) Matt & Zooey are Zooey Deschanel (inset) and M. Ward, the indie duo that performs as She & Him, and they’re among a growing number of artists — the Black Crowes, Jack White, and Yeah Yeah Yeahs are a few others — who think camera phones interfere with sight lines and are generally distracting. We’re told the photo ban was enforced at the Pavilion by a beefed-up security crew that roamed the aisles looking for offenders. “I wouldn’t say they were super aggressive,” one fan told us. “The woman that came over told me to shut it off and keep it off.” Geez, if Deschanel is so camera-shy perhaps she shouldn’t have her sitcom — she stars on Fox’s “New Girl” — or perform onstage.
