For his latest project Reiner Riedler is working with a completely new "camera-less" technology. His negatives are made of cotton cloth treated with sensor dyes. The material is thus reactive: when in contact with sweat, a chromatic processis set in motion and the background changes color from pink to yellow. The fabric is placed on top or under the sweaty bodies for a few minutes and there is only one attempt for each “exposure”. Following the absorption of the sweat, a photographic reproduction of the "imprint" is made, after the colors pink and yellow are converted to grayscale. After the reproduction, the originals are washed as they fade or even disappear after a short time due to environmental influences. What is exhibited are the positives aspigment prints and one original imprint. The fabric has been specifically developed and produced by the research institute “Fraunhofer Research Institution for Modular Solid State Technologies EMFT”.
