Lake of Staz
A picture with a typical mountain lake view in Switzerland. There is a beautiful pine forest at the shore of the lake, and a mountain covered by snow, behind the forest. The lake itself is not frozen, the photo could be taken in end of autumn, the exact season depends on altitude of the lake, too.
The photo could have been taken from a boat on the lake, or very close from the shore - we see water, and not the shore, in the closest plan of the picture. The sky is a deep blue (this also suggest a high altitude), perfectly cloudless. There is a mild light coloring in golden yellow the tops of the trees.
