Photographer Reiner Riedler has discovered sweat as an artistic form of expression.Fascinated by the image captured by the sweat on his T-shirt after jogging – like a spontaneous self-portrait – he has used the sweat produced by others to create a series of images. In order to achieve this, he approached the renowned Fraunhofer Institute in Munich which provided him with a special sensory material that could be placed above or underneath his perspiring models. In doing so, Riedler used the sweaty body as a kind of rubber stamp to create life-size negatives. He then photographed these and transformed them into monochrome paper prints.
