Thanks for those tips, madeeds. I think it's the transitions and the orbits of the objects in the room that fell short, as you said. I'm actually at that location today, but we're using one of the instruments in the room to take data, so we can't turn on the room lights. I'll have to wait about a week before I get another crack at re-shooting that sequence.
I'm curious about #1, though: Any particular reason to shoot the pano at arm's length rather than on a tripod, rotating the camera about the lens's nodal point?
Thanks again for the feedback. It'll be a do-over.
