WOW!
Looks like a great spot to paddle and some great cliff jumps!
Got a sense of photoshop about it though
I'll call photochop on that one.
The long exposure required to make the waterfall look like that would have blurred the paddlers, unless somehow they managed to stay perfectly still while on water??
it could have been done in two shots, one with the paddlers at a fast speed and one with just the waterfall at a slow speed and then the two images merged together.
nice scene all the same.
