Beautiful. I'd be curious how this shot was taken. Typically if you look to the top/bottom you can see the connection point where the camera was resting but I can't seem to find it in this pic.
Although I would recommend watching the entire thing, the relevant bit is around 5:30.
Spoilers:
For anyone who doesn't want to watch the video (or cannot watch the video), they took all of the pictures they could with the camera mounted in one direction, then turned the camera rig upside down to finish taking the pictures. Since the rigging was now in a different location, the boom could be removed from the final product.
