This is an HDR of my Barton Dam image. I originally took 9 shots of varying exposure and the image I originally posted was just one of those images. I decided to try Photoshop HDR on the full set and came up with this image. In reality only the dam itself is HDR. The water came from one image and the sky came from another. The floating items in the water were blurry when multiple images were combined and the trees weren't sharp because there was some wind that day. I also did a Photomatix HDR version. I did a couple of those which ranged from 'mostly realistic' to very surreal.
