Exact same photo as below. Processed differently:
1) This photo was processed using Photomatrix Essentials 3.0 which is specifically designed to work with HDR photos. It is a stand alone program and is comparatively easy to use. There is a good tutorial on their web site. $39.95 online download.

2) The second post below, was processed by using the Corel Paintshop Pro 3X. Not a steep, but a longer learning curve and somewhat complex. $49.95

Personally, I like the Photomatrix Essentials processed final product better. Clean, sharp image and full of definition. But you be the judge and let me know. Cheers!
