A note on photographing Uzbekistan in the season of Chilla, the 40 hottest days of June and July: It is confounding, this strong, overpowering light throwing everything in the frame into extremes. There is no middle ground, only the black of shade and the stark, blinding white of sunshine. In a sense this serves as a metaphor for the extremes of this land. Temperatures that range from 42 degrees Celsius in summer to -30 in winter, geography that includes harsh desert and verdant valleys, a history that has accommodated the devastating invasions of Alexander and Chengiz Khan as well as philosophies as diverse as Zoroastrianism, Buddhism, Judaism, and Islam to the now extinct traditions of Manicheanism and Nestorian Christianity. If there were periods of blighted darkness there were also periods of extraordinary illumination, where the cities of Samarkand and Bokhara, situated smack in the middle of the caravan route between the west and China, glowed with the fabled wealth of its buildings, and its stars: the philosophers, artists and artisans, poets and scientists.
