I just did an interesting thing that I never thought of before.
I normally do my HDRs in Photomatix, and then make adjustments there as well once the merge has taken place.
This time, once I was done in photomatix, I took it over to Lightroom to make further adjustments.
Here is the original HDR created in photomatix before I took it to Lightroom.
I thought the truck mirrors were a little distracting.
