The photo was captured by photographer Walter Monticelli of the UK during his visit to the central city of Thua Thien-Hue.
Speaking on the National Geographic website, Monticelli said that while he was walking between temples in the ancient Vietnamese capital, he heard a faint melody playing in the distance.
“Following the sound, I reached a room in which a group of women wearing traditional clothing were playing music with traditional Vietnamese instruments,” says the British photographer.
“I’d been standing there for a while taking in the sound when I noticed this lady sitting next to the entrance enjoying the music her friends were playing,” he added.
Elsewhere, the first prize in the People Category went to Claire Waring who captured a stunning image of ice fishing on the frozen sea in Hokkaido, Japan.
