Ezra Petronio is the brain behind creative agency Petronio Associates, and visionary behind Self Service Magazine—literally, he shoots those amazing polaroids. If you're unfamiliar, maybe you remember our collaboration last spring? His Instagram, @EzraPetronio features outtakes of shoots over the years, with subjects ranging from Ciara to Marc Jacobs. Maybe not taken with an iPhone, but definitely 'gram gold.
