Wow, this HDR Panorama is absolutely great !
As described there a panoramic tripod head was used to do this, and a lot of very professional work...i found some interesting informations for building cheap panorama tripod heads
here...
I create "normal" panoramas (free hand), sometimes the CHDK grid can be helpfull. I get best results with panotools &
Hugin ...
I also tried to use the "edge overlay" from hiker_jon, but until now this feature is very unstable on my cam...
could it ever be possible to even have the camera do the stitches automatically in-cam?
The stiching process need lots of processor power (for 6 x 5MP ~ 10-15 minutes on my A64-3400 CPU) , the cameras cpu can't do this, also the automatic stitching isn't perfect - i almost have to arrange many points hy hand.
A discussion about panoramas with CHDK support sounds good for me, there are many things possible with CHDK enhanced Canons.
