S75 is a project by Petra Stavast named after the Siemens S75, a mobile phone that was launched in 2005. It was Stavast's first phone which featured an integrated camera, with a maximum resolution of 1280 × 960 pixels. The portraits appearing in this book were photographed by Stavast in Amsterdam and Shanghai between 2006 and 2008, exclusively using the SiemensS75, deliberately exploring its limited technical specifications.
