I don't know why it is yellow. Maybe because of the sun and the moss on the rocks, or the rocks are yellow... I thought it was interesting and I shot it.
A strange effect indeed Milka, seen and captured very well. Are you sure that the rocks don't contain gold? If they may contain it, I prefer to see an image with you as gold digger, lol.
Well that's a good question. Maybe it is the mineral content of the rocks it flows over, but whatever it sure makes for a fine image with lots of really nice texture.
