A keen observer of the urban landscapes of large cities, Castella has shown over the years displayed an artistic journey that has traversed industrial realities, landscapes across the ocean with the African-American communities of Mississippi and Tennessee, Renaissance painting and architecture, and more recently has focused on the representation of the plant kingdom and nature in urban captivity. There is no opposition or contrast, but intricate logic about photography and about representation, light, colour, and point of observation.
This art-nature connection also lives in the printing method Castella uses for the photographs made from Japanese semi-transparent mulberry paper, which has a crucial role in the works’ conceptual development as well as perception.
