Not a focus stack. A 2 row panorama, same focal length, same exposure, roughly the same focus at infinity (landscape image).
The panorama output is fine. It's just not repeatable, even with the exact same input files, and no changes to the .pto file. I literally select 'stitch' twice (exposure fused from any arrangement, optimal size, no resizing set in preferences, all other values to default), three times, four times in a row without changing any of the variables, and each output panorama image is different. See the gif I posted above. I don't understand how the algorithm works, that the same exact variables produce different results, unless there is some random seed somewhere. What I'd like to do, is to produce panoramas with consistently matched pixels, so that I can manually blend differently stretched jpgs derived from the same RAW files.
