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.
