I shot it at f22 @ 5.2 seconds.
Large dof and I figured the longer exposure would give me the lovely swirl in the water. That image has won an award...I have sold it as well as have it hanging in my loungeroom. It's called Serenity. It was taken at a nearby mountain range and I put myself at some reasonable risk to get it. We had recently had some very major flooding so carrying my tripod with camera attached I had to climb down into the stream over rocks, slippery mud and little waterfalls.....it was interesting but certainly worth it.
I had it printed in metallic which did amazing things to the colours and texture. The photo on here really doesn't do it justice.
