In his documentary PARADISE THREATENED, Markus Heltschl opens up insights into the work and life of the color photography pioneer, Heinrich Kühn. Heltschel portrays the life and work of one of the most important photographers of the early 20th century who is also considered the world's best autochrome photographer. "Artistic, sensual and intense masterpieces are at the center of his work. His visual language and pictorial excerpts anticipated the aesthetics of Modernism towards the end of the 19th century" (Artclub Imst)For his film, Heltschl was able to win over well-known artists such as Jeff Wall, Peter Weibel (ZKM Karlsruhe), Monika Faber, Peter Weiermair, Uwe Schögl, Ulrich Pohlmann (City Museum Munich), Alexander Kluge, Florian Ebner as well as Heinrich Kühn's grandchildren.In 1907, the autochromatic photoplates of the Lumière brothers debuted on the world stage and marked the beginning of commercial and artistic color photography. Together with Alfred Stieglitz, Eugene Smith and Edward Steinchen, Heinrich Kühn coined this new art and presentation form. Kühn, a medical doctor, developed his own lenses and left a fundus of over 300 autochromatic patients.
