Mark Neville’s photographs often focus on difficult circumstances, such as hazardous waste dumps and war, as well as the latter’s offshoots like post-traumatic stress disorder. In his new exhibition, titled “Child’s Play” and which features works collected over a 15-year period, children and the importance of play in their lives stand front and center. The theme may sound like a respite from the unpleasant realities Neville usually tackles with his art, but the catch is many of the children in the photographs are pictured in hardly livable places: a refugee camp in Kenya and a war-torn region in Ukraine, among others. In these dangerous environments, play is a breathing space, according to Neville. Play is “an outlet, a release, a kind of therapy,” the photographer said. “It allows children “to make sense of the horrors going on in the adult world and deal with them.” “Child’s Play” was launched on Feb. 3 and will run until April 30 at the Foundling Museum in London.
