Hermann Fösterling, German photographer, painter and printmaker. I am impressed by his heliogravures (photogravure), it is a difficult art to master. These images are all from the series 'Torsi". All printed from a copper plate on handmade paper.
Photogravure is a photomechanical process, using a light-sensitive gelatin tissue, film positive, copper plate and etching fluids of different strength. Check over here if you like to learn more about this technique.
