In an interview with The Huffington Post, Chris Ozer revealed that he joined Instagram on the day that the app launched, but he was by no means a professional photographer at the time. He started using it casually at first, but the studying and practice began to pay off. “When I left my desk job I had enough photography gigs lined up and savings to last me about three months,” he said. “It was a huge risk but it has paid off in ways I couldn't have imagined.” Ozer has since worked with Nike, Samsung, Facebook, and other big names.
