nature meets portraiture | living grass portraits

British artists Heather Ackroyd and Dan Harvey have created a series of large scale portraits using living grass as their canvas. The artists project a negative image of a photograph onto a wall-mounted sheet of grass seedlings on clay, in a dark room, and photosynthesis takes care of the rest. The grass grows in shades of green directly proportional to the amount of light they receive, thus creating a tinted image of the photo.

Up close it may just look like a field of grass, but from far away the living image looks like a verdant version of the original photograph. The portraits can last for months, even years, becoming sharper as they grow, then slowly fading away.
