Vertigo-inducing images from one of the world's most densely populated areas.
When French photographer Romain Jacquet-Lagreze moved to Hong Kong four years ago he was inspired to capture the feeling of living in a high-rise environment of a city where seven million people are squeezed into an area of just 426 square miles.
His first 'Vertical Horizon' collection proved so popular after pictures went viral on the Internet that he's produced a second, illustrating the city's ever-growing skyline.
"Hong Kong is a big city which is evolving very quickly so I was confident I could find some new spots," says Romain. Areas such as the Kwai Tsing and Western districts, where he took some of his favourite pictures, are developing so fast that they changed even during the three months he spent on the project.
