Alpen-Panoramen, Panorama der Alpen

On the Vezzana, I experienced the luck to have the sun rising exactly while I was passing there with my CCW sweep of the horizon.

39 images, Canon G1X, 98 mm equiv, ISO 200, f/5.6, 1/125 sec.

Shooting such a number of images by means of a compact camera takes time: in this case, according to the Exif data, little less than three minutes, which in this particular moment of the day is by no means a negligible interval, for luminosity concerns.
The work produced by Hugin with exposure optimization presented some annoying transitions, so I tried out the following method, all done with exposure interventions turned off:
- blend all images, with exception of some of the first ones (three here), in order to have a hole at the cut, and no superposition between the first and darkest and the last and brightest;
- blend separately a "patch" made by the excluded images;
- temporarily apply the patch over the panorama, and then apply to the latter a Curves adjustment (stronger than expected for three minutes!) aimed at compensating the luminosity gap now clearly visible at one side of the patch. Adjustment, of course, faded throughout the whole picture width (here, some 75000 pixel);
- definitely apply the patch with a suitable opacity fading at the sides of the hole.
I expect some panoramist wiser than me to point out that all this may be accomplished in some much simpler way, maybe even with a suitable option passed to a suitable program - not Hugin, I guess.
The process in itself, however, introduces an overhead truly negligible with respect, for example, to the time needed for an Udeuschle-based geometric control of an object like this.

In any case, this is to a certain extent an experimental work!

Do not claim the discovery of a new Alpine giant right of the Marmolada: it is only a nice, bulky cloud!
