What a difference ten minutes can make at the end of day in terms of light and color. I love the rich blues of the sky, the sun grasses, even the whitish calcified Tufa in the background. I made my own image of this scene about ten minutes after you did -- the sun had set, the tufa turned dark, the reflections became pale and the ducks began to go home.
