Hi Bruce,

These images were not actually generated by stitching multiple images together, they are just panoramic crops. However, I do generated panoramas from multiple shots when I have to. As surprising as it may sound, I actually use a free utility that came with an old HP printer from years ago!

Unfortunately this immensely simple tool works so well that I never went looking for anything else, so unfortunately I can't actually offer you a recommendation.

Sorry!

Bart.
