Hugin

Hugin is a panorama stitching program: it finds common points in a series of overlapping photos, aligns them, corrects lens distortion and perspective, and blends the seams with Enblend. With Enfuse it can also merge a bracketed exposure series of the same scene into one balanced image. An engineer can use it to create a wide image of a building facade, hall, bridge or construction site from several photos, and to document existing conditions before work. Limitation: the interface is technical, and the official macOS build is old and does not run on Apple Silicon; on Linux it is installed from the distribution repositories.
