What is it like to travel with the Rolling Stones as their official photographer? What are the challenges of getting that decisive concert shot when you’ve got only two songs and you’re standing way back at the soundboard? What are key tips for photographers who are working with music stars and their handlers?

Those topics and more will be discussed at a panel on The World of Rock & Roll Photography at 7 p.m. Thursday at the Mpls Photo Center. Panelists will be Twin Cities music photographers Steven Cohen and Tony Nelson along with longtime Chicago photographer Paul Natkin, who has traveled with the Stones, shot magazine and album covers, and has become Buddy Guy’s personal photographer.  Star Tribune critic Jon Bream will moderate. The discussion is free.

The panel is a prelude to the Rock & Roll Call for Entry Exhibit, which opens on Friday at 2400 N. Second St., Mpls. The exhibit features music-related photos by photographers from all over the United States and as far away as Slovenia and Uruguay. Natkin, who took the photo of Keith Richards above,  served as the juror. Cohen received the first-place prize.
