A girl fixes a boy's tie as children wait to walk onstage to perform at an outdoor concert on Cat Ba Island in Halong Bay, Vietnam. The boy wasn't too fussed about the state of his tie and was more interested in waving his flag around. I waited for the flag to unravel so it would silhouette his profile against the stage lights. In post-production, I raised the contrast to emphasise the rim lighting around the girls.
