@Carmelo_DrRaw Thank you very much for taking your time and sharing your “new” workflow!
I loaded this image, applied your preset, and exported to a tif file. I did the same to other two images that produce a panorama.
Unfortunately, Hugin doesn’t seem to like these files: after setting up the parameters (finding the points / geometric and photometric optimization), when I click on the GL button (to start building the panorama), it crashes. I tried this for rec2000 tifs as well as for srgb’s. Reinstalled it but nothing.
When I have time I try to test this Hugin/Ubuntu 18.04 on other panoramas to see if the problem is with this new Ubuntu.
Thanks once more!
