Here is my HDR version. i wound up with some sort of halo around the top of the tree on the right side of the image. i confess that after a couple attempts to 'clean it up', i gave up. there is still some stuff left over from my playing around with it, but i didn't see any value in goofing around with it anymore for the purpose of this challenge.

the last one was a lot of fun to see the different results. based on what i wound up with on this one, i really look forward to seeing everyone's results again.
