I shot the 360 panoramas for their ships that are on their web site. I took a 360 pano that is on 360cities.net that shows the Hunt for red October submarine and one of the Jetboats. I will have to try out the jet boat.
If you don't mind my asking, what was your workflow for the HDR?
Did you stack the images individually for each view(and then stitch separately), or let a stitcher like PTgui do it all from a ton of images?
I use the details enhance and hdr mode in photomatix using the bracketed set of camera RAW files. I enable alignment by feature and check do not crop. I use 16 bit TIFF and a HDR format such as radiance or openEXR. I then stitch the images in Ptgui or Autopano Pro. Then I do edits in CS3 extended. The bridge had 7 brackets per position which took about 15 minutes and 25 seconds per panorama head position.
