Nice waterfall shots, Brant. I spent nearly every summer of my youth in North Conway and never heard for Diana's Bath either. We were usually up at Lower Falls on the Kancamagus or Sabbaday Falls (when you could swim there).

I use SNS-HDR Lite for my HDR work. It's simple and seems to outperform Photoshop and Photomatix Pro, at least in my experience. A little bit of tweaking back in Photoshop and I'm done.
