Scary feeling, you say. Well, I can imagine that, since the color and the waves do look a bit scary, but people here often jump in the water and are carried some hunderds of meters away by the power of flowing water. As about the saturation, I had a very good sunlight on that day, which I think helped me capturing the color of the river. It is indeed very intense in reality, but I don't know why.
