I am in Scotland right now to begin my photo tour here. Today I photographed the interior of the 12th century St. Giles Cathedral in Edinburgh. This is an HDR panorama image of the ceiling. I shot 6 different 'panels' comprising the panorama composition, starting from a ground-level shot on one side of the cathedral and, overlapping each image about 50%, I continued arching my back as I shot higher on the ceiling. At mid-point directly above me, I turned 180 degrees and continued creating more panels until I reached ground level at the opposite side. Each panel consisted of a 7-frame HDR sequence with one f/stop increments. I had to use HDR because the contrast in the cavernous interior was significant. I used 3200 ISO so my slowest shutter speed was 1/45th of a second. This was fast enough with a wide angle to create a sharp picture. I used a 16-35mm wide angle lens set to 16mm. I then processed each panel with its 7 bracketed frames in Adobe Camera Raw using the command Tools > Photoshop > Merge to HDR pro. Once all those panels were completed, I then turned those 6 panels into a panorama in ACR using Tools > Photoshop > Photomerge. All frames used for the final composite were made handholding the camera. CLICK ON THE PHOTO TO SEE ITS ENTIRETY.
