We have had some heavy practical experience here using Panoramic
techniques in our last game. I would say, that for economics sake the
"Christmas Ornament" and a digital works really well. If you want
complete accuracy.. http://www.panoscan.com/ (38,000 US)
We went with a pano head, a EOS 20D and a whole bunch of Memory Cards.
Our goal of course was to recreate the background, and look decent on
HighDef, and the technique of 1 shot up, with 10 around, separated
vertically by 45degrees worked out well. We shot all in RAW and I found
that there is actually about 1.5 stops of extra data since Canon uses a
10bit RAW image. Not as fast, but higher degree of accuracy. Now for
lighting, I have to agree with Joe L., the quality of an HDR image seems
to be more like a Lambert lighting solution, than the strong lighting
you would get from a real Light source. We always bolsterd the HDR
solution with real lights with Exponential fall off.
There is a very cool site you should all check out,
(http://www.cs.ubc.ca/~mbrown/autostitch/autostitch.html ) More of an
intellectual experiment, than a full fledged program, but for tooling
around a bit it's great fun. Easy panoramas, no GUI, and can be pretty
slow, but for a completely automatic panorama, it's nice.

Doh! sorry.
