Panoramic photographs of fantastical landscapes make a bizarre Baedeker to alternative realities in City of Salt, by Nicholas Kahn and Richard Selesnick. The second volume, after Scotlandfuturebog, in an intended trilogy of such otherworldly guides juxtaposes those scenes with similarly inspired texts: Sufi tales, the writings of fabulist Italo Calvino, and parables by the artists themselves. The strange deserts, marshes, sandy shores, villages and fields are often traversed by wandering figures, frequently in peril or precariously alone. Kahn and Selesnick’s process combines sculptural and photographic media. The artists first construct the intricately detailed worlds in three-dimensional miniatures and dioramas, then digitally photograph the scene and populate it with characters in allegorical, though intriguingly puzzling, tableaux.
