I think this is a great shot. It's hard to take these without getting the lens wet, and the slow shutter speed (needed for the low light and great for showing water in motion) probably warrants use of a tripod.
If there was no danger of wetting the lens, then I may have tried to aim the camera up at the chain. It may have been interesting to see the water cascading down past the focal point. If you have some others, maybe you could post them on the ÔÇ£anarchyÔÇØ thread for comparison?
I hope you don't mind. I couldnÔÇÖt resist some minor photoshop color and contrast adjustmentÔÇª Threw in some focus adjustment for reference.
Nice post, Dave!
