After moving on from a career of shooting medium format film for celebrities and high-end clients, a photographer begins capturing graffiti with his cell phone from the window of a commuter train, then builds a device to develop cyanotype prints at home. "I found it fascinating that there were people out there in the middle of the night making art on the side of these train tracks," he says. "It became an experiment of documenting the graffiti. Since I had very little time to make my own art, placing my cell phone on the windows of these trains and trying to capture these pieces of graffiti felt like it was at least celebrating this form of art. On these incredible old walls along the Montclair-Boonton line, there are people making beautiful art along the rail."
