Low cloud and fog is the way I have always found Dartmoor and this day was no different.... Thanks to Alex [link] for taking me under his wing for the day and showing me some of his treasured locations.
Thankyou, yes moving water is fascinating for photography. The trick is to make test shots to see how long an exposure works best and then shot around that shutter speed, taking several shots. Each one will be different and some will work better than others.
What a wonderful shot, packed full of interest and drama - great composition and perspective, exposure spot-on, framing sublime. Terrific! - and in such unpromising weather when lesser mortals (like me) would have stayed home in the warm and dry... well done!
