Did you use a tripod for the HDR shots or can you over lap them like panoramas do? I always thought you would need a tripod for a perfect fitting frame.

I have never tried to do an HDR because I don't know how! I do have CS3 but I rarely use it, I do all my work in Lightroom.

So much to learn about photography for sure and by the time you get it all figured out the rules change.
