Joseph formed the idea for this photograph in 2016 on a visit to Mai Po Nature Reserve in Hong Kong.
Taken within the Frontier Closed Area on the Chinese border, strictly timed access rules meant years of studying tide tables and waiting for the perfect weather. Joseph wanted to convey the story and mood of Mai Po in a single balanced photograph, combining individuals and the behaviour of multiple species in the context of their wider environment, particularly to juxtapose the proximity of the everencroaching urban development.
