Stitching and panorama photo

[rich2005]

Just an initial thought. The Pandora script from https://www.shallowsky.com/software/pandora/ This is ancient but might be more appropriate than the more usual Hugin panorama stitcher. All depends what you want.

A bare-bones demo. https://youtu.be/VRhIsWiekaQ duration just 2 minutes.

Even if it is not what is required, it does show layer masks in action.
