Most people don’t pay any attention to grass and the way it grows, but British artists Heather Ackroyd and Dan Harvey have always been fascinated by it and have found an ingenious way to incorporate it into their art. By manipulating the way grass grows, they are able to literally print detailed photographs onto a living wall of grass that develops according to how much light it receives.
The two artists start by covering a large canvas with water paste and rubbing germinated seeds all over it. They then cover the windows of their studio turning into a dark room, and making sure that the only light that reaches the canvas is projected through a slide of a negative photograph. They then let photosynthesis run its course, and in a few weeks time the grass-covered canvas grows into a living print of the photograph. The amount of light shining through different parts of the negative determines which parts of the canvas turn out a vibrant green, and which remain yellow and undeveloped, making the details of the image clearly visible from a distance.
