Rian Johnson releases a $13 iPhone app that gives photos the look of his films

Filmmaker Rian Johnson and cinematographer Steve Yedlin have released Chromagraph Camera, a $13 iPhone app that gives photos the look of Johnson's films. Rather than editing photos afterward, it skips part of Apple's built-in processing. Controls include how long the shutter stays open, burst shooting and color. It also handles unprocessed photo files from other cameras.
