These unique black-and-white prints are realized in a darkroom using one of the most traditional photo-printing processes, starting with exposing light on photographic paper. Nevertheless, here the light source is laser beams that are programmed to shift with sound patterns randomly generated by a synthesizer, and exposed directly onto light-sensitive paper in a camera-less process. Similar to Hiroshi Sugimoto’s photographic series Lightning Fields, where he applied an electrostatic generator directly onto film, Feng Chen translates invisible signals into images by creating these “portraits of sounds”. The photos inspire an open-minded way of understanding the world around us as a new dimension may emerge when perceived with a different sense.
