Rebecca Wickham’s photographic practice is concerned with the climate crisis and our relationship with the Earth. Primarily focused on landscape, she often works directly with the environment to bring a sense of history and physicality into the work. Once Was explores ecological grief, through landscape and death mask, and asks how to mourn for something other an a human. The work depicts post-glacial worlds alongside death masks made from earth and meltwater, linking human and landscape through grief, memory and imprint, and reflecting on a sense of absence, responsibility and entanglement.
