I've been experimenting with waterfall photography. I always used to argue that natural was best. But I think that was mainly because I didn't know any other way to do it.
Here are two photos of Abrams Falls, in the Great Smoky Mountains National Park in Tennessee. The first was taken at a shutter speed of 1/100, which captured the waterfall as it looks naturally. The second was shot at a slower shutter speed so that the water has a softer, blurred look.
Following is a short video of Abrams Falls:
So...how do you like your water?
