The roughly 60 pictures from the estate of Andreas Züst treat the phenomenon of fog blankets illuminated from below by our civilization, taking on a fluorescent effect. The book covers the most important aspect of Züst's “Himmel” (Sky) cycle: the phenomenon, photographed from the Zürich Bachtel, of wintry fog blankets over the Swiss Mittelland, lit from below by street lamps and house lights. The Swiss writer Peter Weber gave them their title.
