Trope Publishing Company's new Mobile Edition Series identifies fine art photographers shooting in a new way, using mobile devices as their primary tool to capture images, in a category still defining itself. Among the millions of images posted to social media every day, the work of these photographers stands out for its discipline and mastery. Beijing native Cocu Liu's work emphasizes its simplicity, ordered composition, and mastery of light and shadow. An early adopter of the iPhone, Cocu has built his work around the idea that the best camera is the one you have with you. His ability to notice, compose, and capture an image with such spontaneity, so simply, is a true sign of his artistry. Cocu Liu introduces a wider audience to the talent that has won him multiple awards, notice from mobile phone makers, and the admiration of fellow photographers and his over 130K social media followers.
