Most look overjoyed.
Interesting image and gives a good overview of the event. The stitching is rough and ready probably because the camera was either hand-held or spun around on a tripod head without being set up properly for stitching first There's a perfect double face just behind Jimmy Carter which is fun, but given the complexity of the scene the image would need a lot of work to clean it up anyway.
chances are it was done with a Gigapan robotic tripod head.
they are pretty much a set and forget system, then hope it all worked properly.
I have used one a couple of times - once to do a high resolution file of Perth - it was supposed to be printed in the corridor - took 15 minutes to shoot, 90 minutes to stitch on a fairly quick iMac, and when finished had enough resolution to print 10mx3m at 250dpi (thats roughly 30ft by 10ft)
I used a Canon 100-400 @400mm +1.4x converter on a Canon 1DX (18MP)
My picture at a football game was not successful, too many people moving, and the finished file was too big to edit to meet the deadlines i had been set (I told the boss this as i got the job brief, but had to give it a go anyway)
There were a couple of other pictures i did with it as well - none were ever used, or even displayed outside of our department.
