Ackroyd and Harvey: Life on Life

The photograss is back. After their 2012 exhibition 'Salons' saw them literally plant their photos on the walls of the Orangerie du Domaine de Chamarande, British duo Ackroyd and Harvey are at it again. Their eye-catching technique involves the imprint of a photographic image onto vertically grown grass; in practice, this makes for some curious visual effects – walk backward as you face an image and watch it appear to sharpen before your eyes. Catch these unique works before they yellow, fade and die, like the memories that photography seeks to preserve.
