one crucial reason why professional photographers haven't swapped their cameras for smartphones.
Smartphone cameras have yet to match high-end digital cameras especially in low-light settings, said Jun Michael Park, a freelance photo journalist in Seoul.
''I still wouldn't switch. Smartphone's small camera comes in handy, but when I take pictures I always think about getting it printed, having a show, or getting them published,'' Park said.
Winning over photographers like Park could be the next trophy for smartphone makers.
