Trees - when I walk through a forest, most trees I just walk by. Some I look at, nothing happens, like when you walk through a busy street with countless people.
Then - without a hint, without any obvious difference - I feel an urge to get closer to a tree. I touch it and feel earth. The power, the mystic that reaches the tree through its roots.
When I have my camera with me I make a snap of a piece of bark. That takes a while until the image is right, it feels like the tree itself is guiding me to find the right area.
