When you can barely see flecks of starlight shining upon a city - where the lights never turn off, where the night sky is perpetually shrouded in a haze of murky light - you're left with the thought: what would happen if there were a power outage, just for five minutes? What would the heavens reveal? 

To create these photo composites, Cohen travels to another place in the world on the same latitude, where the sky is clear and there is little light on earth to interfere with the starlight. For Hong Kong's cityscape, the sky is that of the Western Sahara desert that's more than 12,000 kilometres away; for Paris it's northern Montana; and New York gets the stars above the Nevada desert.
