Waikiki, Honolulu, Oahu, Hawaii from Diamond Head to the Ala Wai Boat Harbor looking mauka (toward the mountain).
This was actually my very first attempt to create a panorama photo... and it's holding up fairly well even with experience and better software. I didn't know very much about what I was doing at the time and as a result didn't overthink the process and mess up much other than chopping off the tops of all the tall buildings (aargh!).
The original post processing was also done without much experience and the resultant pano (via Adobe Elements 3.0) wasn't very satisfying. This version has been rebuilt using PTGui Pro vers 7.0.0beta5 and is much better. Proving once again that ignorance really is bliss, note that faint whisp of a rainbow just to the left of the Rainbow Tower. When the shutter snapped I don't think I even noticed it!
