Hi Hermen, talking about natural light, heh? Well, this sure beats mine where natural light is concerned.... But then again, my last series is taken at night...:) Excellent tones, and a very appropriate saturation, emphasising the warm / soft light on the birches against the dark, threatening sky. Very well captured, and a very beautiful shot.
Great light in this image, it looks especially good against that moody, dark sky. I also like the repitition of uprights. The light and dark bark on the tree trunks reminds me of zebra.
