Panorama are gift of digital photography. Hardware tools abound, and software makes easy stitching possible, even with hand-held images.  I’ve successfully made panos, or example, from images created hand-held from a drifting kayak. If close foreground is in the image, though, exacting technique is required. For backpacking, I like my home-made wood tool;  4 extra ounces  in the pack is all I need to make exacting, close-foreground, single-row (vertical) images that create huge, detailed, panorama files.
