I love the first three shots. It almost looks like the water rolling over the rocks is smoke... or dry ice. Nice effect! It could even be mistaken for a painting!
Thanks,
No, I didn't go on a raft. I just happened to be there when a group of rafts came floating by. There were also a bunch of kayaks coming & going but I didn't get any shots of them.
I have been on a white water rafting trip and I recommend it, it's great fun.
