In HAAF (2020), Julia turns her attention to methods of traditional fishing, working alongside some of the last remaining haaf netters on the Solway Firth. This film, shot in black and white and hand developed, evokes a bygone era through texture and tone, while interview commentary meanders between yearnings to preserve the millennia-old tradition and complex discussions of the arbitrary nature of borders. Through the telling of Scottish-English fishing rivalries, water is revered and imbued with power beyond tools and industry – it is the tide that dictates the line in the Solway Firth between the two countries.
