Earlier this year, Unicef initiative NextGen asked eight photographers, including Jack Harries and Cyrus Mahboubian, to respond to the concept of human migration. “Living in London,” says Mahboubian, “we find ourselves largely detached from the ongoing refugee crisis, despite its staggering scale. I wanted us to inspire fellow Londoners to have a conversation about it.” For the project, called Migrate, the photographers used Polaroid cameras, and film supplied by The Impossible Project. By using instant, says Mahboubian, “the interaction with the subject becomes more personal, shooting fewer pictures, talking more”. The photographs will be on show at Omeara, London SE1, 29 August to 2 September; a book is available online.
