I love Bull Creek in Austin - it's near my home, and it's a great little greenbelt/trail/park kind of thing. I especially love it when there has been rain, like now. All the waterfalls are just rockin' right along. That makes me happy.
This was a single exposure instead of an HDR. I love to shoot HDR as you probably know by now, but with waterfalls I am about 50/50. I find that at least half of the time I just go with a single exposure. This one was f/13 at about 2 seconds. Sometimes the simple approach is best.
