Other than a 'test shot' in at home to ensure I had the bracketing set up correctly these are my first HDRs reasonbly happy as I have used Luminance HDR (free software)
I used to do quite a few, and very often. I think it was phase. I think HDR is a great option, but right now, at this point in my path, I just don't have much interest. As everything cycles, I'm sure I'll be re-visiting multiple exposures in the future.
