Silent World by the German-French photographer duo Lucie & Simon is a series of photographs capturing crowded cities with no one in it. From New York and Paris to Beijing, these photographs are an eerie depiction of some of the world’s most recognizable and busiest public outdoor spaces vacated and devoid of crowds. In Silent World bustling urban environments become apocalyptic ghost towns.
To reach that effect, Lucie & Simon use some camera trickery. They use neutral density filters that allow them to limit light entry without closing the aperture or increasing the shutter speed, allowing for super-long exposures which make moving objects like people and cars essentially invisible, while only immobile structures remain.
