Watch Carefully is a work developed from a set of photographs taken in China in 2014, and is a reflection on the erosion of intimacy in modern life. The pair of images - A Boyish Secret and A State Secret - are an intriguing set of contrasts: most fundamentally the striking innocence of the boys, compared with the sinister presence of state surveillance but also in the organic warmth of a sparkler held between young faces put against the observed emptiness of the large square washed in the synthetic light of the tower.
