Welcome to the planet Nagoya!!
Now we are on the side where I used to live and work for about three and half years :-)) For those who is wondering what “TTI” stands for: “Toyota Technological Institute”.
A little bit about how it was done. Using Nikon D80 with 18-200mm VR Nikkor lense I first took 23 NEF (RAW) files, then processed them with CaptureNX to make several different exposures. After that with the help of PTGui created a normal 360° panoramic image. With a simple trick I could use absolutely same control points and alignment parameters for all exposure sets of images, so final panoramas were almost 100% same. In order to avoid some tonal or contrast mismatches at the opposite edges of panorama as a result of HDR processing, I first created “planetoid” images with different exposures. And making the HDR and ToneMapping by Photomatix was a final step.
Final touch was done in CaptureNX as it has a unique tool called “control points” (it saves a lot of time), and also it allows saving the modified image in NEF format preserving all the workflow so that later you can open it again and modify some control points or other settings.
