Louis,
Thanks that was interesting.
Dr Bob,
I also have an EOS 5D and have found a budget solution
to the Fisheye problem:
http://www.zenit-camera.com/zenitar_m_fisheye_lens_for_canon_eos.htm
Here is someone else's review of the lens:
http://www.baltimorecameraclub.org/HTML/Zenitar_fisheye.html
I find that it works well for for VRs shot tripod
mounted
http://geoimages.berkeley.edu/worldwidepanorama/wwp907/html/GeorgeRow.ht...
and for ones shot hand held:
http://veryderry.com/db/location.php?pano=48
On the tripod I take six images, hand held it will
sometimes be seven or eight and in each case I add a
sky and a ground shot. I stitch using HugIn, (no need
for DeFish since I spotted the "Enable rotation"
preference under "Fine tune") and render as a Cubic VR
using CubicConvertor and CubicConector.
all the best
George
