Whoah! That's rich. I love it. I like the balance between the really blurred areas and the ripply parts. This makes me want to touch the water. I can imagine putting my finger in and feeling the wetness. Makes me want a drink of cold creek water.
You indictaed that you shot this with Velvia 100F, but it looks like a toned black and white. Did you shoot it on Velvia and then scan the slide and convert it to black and white?
