This panorama was taken from the roof of my apartment building.
I used my Sigma 10-20mm to take three vertical-orientation photographs covering a total of 167 degrees.
Each of the three shots is actually a six-frame HDR, ranging from -2 stops to +3 stops in 1 stop intervals.
The resultant RAW files were processed twice, once with a white balance setting for the sky, and once with a white balance setting for the city. Each of these two sets of output files was then stitched to form two HDR panoramas, once for each white balance setting.
Finally, the two panoramas were blended to form the final result, above.
Definitely best viewed large, press 'L'. Don't forget to press 'F' to fave it, if you like it!
