Amazing and unique portraits by England based Heather Ackroyd and Dan Harvey. They take something we all take for granted, grass, and turn it into a fascinating medium for artistic expression. Their unique art of portraits are created by exposing plots of seedling grass to light through a custom made negative, making the grass grow in different shades, from yellow to green lights. In essence, they strap up the process of photosynthesis and capture chlorophyll to fix images to growing grass. They wait just a couple of weeks and you’ll bit by bit start to see faces emerge. If they wait too long and these images start to disappear, just like a photograph will eventually faded up with colors. Interestingly this artistic duo behind history trees seems to be a collection of nature effects of light which grown towards certain importance of natural portrait artworks.
