Love this series by British artist Zander Olsen called Tree, Line. In Zander's own words: "This is an ongoing series of constructed photographs rooted in the forest. These works, carried out in Surrey, Hampshire and Wales,involve site specific interventions in the landscape, ‘wrapping’ trees with white material to construct a visual relationship between tree, not-tree and the line of horizon according to the camera’s viewpoint." Stunning. More on his website here.
