Lovely, clear shots taken at the right time of day for beautiful lighting. However, you'd need a big wall to hang such prints of a sufficiently large size to fully appreciate the fine detail. Are you selling prints like these?
The horizontal pano looks as though it's comprised of 5 or 6 images with camera vertical, or maybe 2 or 3 images with camera horizontal. Which?
Were there any problems stitching these or did the fully automatic modes of PTGui handle it easily?
Now I've seen what a perfect job can be done by programs such as Autopano and CS3 Photomerge with 3 or 4 images (sometimes, anyway), I intend experimenting more with handheld shots to get an idea of what sort of images can be automatically stitched. Having to set up a tripod, assuming one is carrying a tripod, can be a pain. Lightweight ballheads don't seem useful in my experience.
