<<This guy has an interesting discussion of panos, & a product called

This guy is clearly serious.  Let's see, he measured and plotted 1) Panoramas 
per year, 2) days between image capture and image completion --mine would 
require a log scale on the abscissa.---,
3) Days spent photographing by year, 4) Days spent assembling panoramas by 
year, 5) Average panorama Megapixels per year 6) Average component image count  
per year 7) Panoramas by lens focal length......and on it goes.

He uses  PTAssembler  which he constructed.  I have read that Max Lyons  
independently developed, using mathematical methods, the "recti-perspective" 
projection  (sounds like a technique used by gastroenterologists) which is 
essentially identical to the Panini projection which was rediscovered about the 
same time. The backstory is interesting--TK Sharpless was involved with 
developing Hugin in 2008 and  co-rediscovered an 18th century painters' 
technique for rendering wide views in a natural looking perspective .  It was 
named in honor of Gian Paolo Pannini, an 18th Century Roman painter and 
professor of perspective.  This projection seems to work very well for many 
pano landscapes. 


Moose is very very good at analyzing this panorama projection conundrum  as he 
has the rigor of a physicist to accurately isolate the problems with an image,  
the eye of an artist ,and photographic processing chops to make it all happen.
