From the article from The New York Times:
Fourteen years ago, the mother of a gender-nonconforming son organized a “summer camp” of sorts, where her child and others like him could wear frilly pastel nightgowns and tend to their My Little Ponies together. Only three other families showed up that first summer, but the camp grew quickly. It was called Camp I Am. In 2008, the photographer Lindsay Morris took her son there and began taking pictures of some of his fellow campers. More than a decade later, she asked many of them to be photographed again as they entered adulthood.
