What Major World Cities Look Like at Night, Minus the Light Pollution | Collage of Arts and Sciences:
Three years ago, Cohen embarked on a grand plan to help remedy this situation. He’d give city dwellers a taste of what they were missing. The photographer crisscrossed the globe photographing cityscapes from Shanghai to Los Angeles to Rio de Janeiro, by day—when cars’ head and taillights and lights shining from the windows of buildings were not a distraction. At each location, Cohen diligently recorded the time, angle, latitude and longitude of the shot. Then, he journeyed to remote deserts and plains at corresponding latitudes, where he pointed his lens to the night sky. For New York, that meant the Black Rock Desert in Nevada. For Hong Kong, the Western Sahara in Africa. For Rio and São Paulo, the Atacama Desert in Chile, and for Cohen’s native Paris, the prairies of northern Montana. Through his own digital photography wizardry, Cohen created seamless composites of his city and skyscapes.
