4. Mike Lerner
Location: Brooklyn, NY
Mike Lerner is Justin Bieber's official concert photographer, which means that it's his job to document one of the biggest popstars of our time. Thankfully, he does it well, and you wouldn't even realize that he's only been shooting professionally for two years. He networked his way into shooting The Bravery and Katy Perry live, eventually getting his name out there enough to attract attention from Bieber's people. His live shots of Justin set the standard for what live music photography ought to be.
