A photo of a woman spotlit by the glow of her phone on a crowded train has been chosen as the grand-prize winner of the 2014 National Geographic Photo Contest.

Selected from more than 9,000 entries, the photo, titled A Node Glows In The Dark, was shot at Ocean Park in Hong Kong. The photographer, Brian Yen of Hong Kong, said: "I feel a certain contradiction when I look at the picture. On the one hand, I feel the liberating gift of technology. On the other hand, I feel people don't even try to be neighbourly anymore, because they don't have to."
