Beth Moon has spent the last 14 years photographing the world's most ancient trees. Her latest series, "Diamond Nights" captures these same trees, (mainly baobabs and quiver trees in South Africa, Botswana and Namibia,) illuminated by starlight. "Our relationship to the wild has always played an important role in my work. This series was inspired by two fascinating scientific studies that connect tree growth with celestial movement and astral cycles," Moon explains on her website. Results of the first study, indicated that cosmic radiation impacted on tree growth more than rainfall or temperature. The second, found tree buds change size and shape in direct correlation to the moon and planets. Moon, from San Francisco, was led to the site of each tree by a guide during the day. She would then return to the site at night, using 30 second exposure times to avoid capturing star movement. Check out the eerie results!
