Sci-Fi or science? Markus Krottendorfer’s slideshows with infrared film make it difficult to distinguish between the two. He is as fascinated by the world of scientific research as he is by fictional speculation. He portrays a Martian robot on a Californian test site imitating the movements of its counterpart on the red planet. The vast solar telescope of Kitt Peak as well as Biosphere II appear in hues of pink and blue as though they really had been photographed on another planet.
