Flo has been using his Afghan Box Camera at festivals such as Burning Man, Afrikaburn and Nowhere since 2013. It all started with a shoebox and turned into a very elaborate, high-tech Box Camera with an Arduino board measuring light, a 3D printed obturator, LED light and LCD screen. No wonder Flo is a software engineer and hacker. He prints his positives inside the camera. He usually gifts his pictures to the people he photographs.
