Waterfall with Beech Leaves

I had stopped in a layby for a cup of coffee and could hear the sound of this waterfall across the road. When I went to investigate I discovered this scene with the moss covered rocks sprinkled with autumn leaves. The contrast of the green and orange was irresistible.
It was fairly dull under the trees and this image needed an exposure of several seconds, although it needed compensating for the darkness of the image which was well beyond mid grey.
