Update. I ended up downloading the Photomatix Basic version. Here are a few of the shots that I put together with it in case anyone else was interested in the freeware HDR stuff. These were all either with 2 exposures or 3 exposures. I wanted to do this because when the leaves are off the trees any long exposure shots always blow out the background sky. So I wanted to take some underexposed shots and combine the shadows. The Photomatix Basic did that for me, but there were a few that looked goofy with it.

This one is a little weird. Not sure if I like it. It wasn’t done in HDR necessarily, just combining the shadows.

This one would’ve turned out a little better if I had remembered to turn my circular polarizer the right direction.
