Venice Biennale: Helen Sear's exhibition opens

The Welsh fine art photographer Helen Sear has welcomed the first visitors to her show at the world's largest exhibition, the Venice Biennale.

Sear, from Raglan, Monmouthshire, who is the first solo female artist to represent Wales in Venice, uses large-scale video and stills photography at her venue in the Italian city.

She told BBC Wales arts and media correspondent Huw Thomas about The Rest is Smoke and how she wanted visitors to get a sense of different speeds of viewing it - and you can watch a time lapse of her work Stack being installed.
