He became known to a wider audience through the experiment "500 faces", an extension of "50 faces", a project he carried out in 2013 in cooperation with Kunst im Öffentlichen Raum e.V.. For this, he recorded 500 unknown people on black and white Polaroids in a mobile studio at the Umsonst und Draussen Festival - completely without a mask, happy, serious, exuberant or sweaty. Just the way they were at that moment. For the exhibition, the pictures were scanned and shown unretouched. An exciting project that puts people in the foreground, with the goal for people to meet and once again consciously perceive each other - just as they are.
