Hart’s most recent series FRAGILE (2020-24) is a personal and poetic reflection on nature made in the landscape close to his studio in the east of England. In response to the poem Trees At Night by the late Helene Johnson, poet and author of the Harlem Renaissance, Hart made work every month in the same locale over the course of four years. In keeping with his longstanding practice to work in analogue, the series is made on medium format film cameras. FRAGILE was published in 2024 by Dewi Lewis and was nominated for the John Ruskin prize and the Deutsche Börse Photography Foundation Prize in 2025. Images from the series have featured in numerous other publications including National Geographic Magazine, Now Voyager and FRAMES.

Works from FRAGILE currently feature in the exhibition In het Bosch at Galerie van Blijkshof in The Netherlands until May 2026. Other notable exhibitions include : Trees Observed (Fen Ditton Gallery, Cambridge, 2024) and The Royal Academy Summer Exhibition (Main Galleries Burlington House, 2024).
