I downloaded the three-image alaska 'panorama'. It uses translation
parameters, which lux does not process, hence the failure. The image is
not a panorama: The three partials have been taken from different
positions, always facing the facades, probably several meters apart.
It's an attempt to create a 'street view-like' image mosaic from a 3D
scene (dodgy, mosaics are for 2D content), hence the translation
parameters to attempt a fit, which works okay-ish because the facades
are roughly in-plane.
The Alaska one is the only one I didn't try.
First on the list... ;)
But I never paid attention to the TrX, TrY and TrZ parameters. My 2
image pano is a hand-shot pano which I initially used for parallax. And
yes: it needs translation parameters as well.
It is just small and handy and a quick test.
Just try any 'real' panorama with no translation. And the black output
was a different matter, and should be fixed if you pull and build again.
I will take one of my other panos, but lately I don't do much panos.
Only bracketing and noise reduction with ais and enfuse. (burst mode
with a number of photos. I never had nor will buy a full-frame so I
sometimes make burst-mode photos and ais/enfuse them to remove the
noise. Works great)
I will test pv/lux as well with noise reduction.
If you do simple HDR blending or an exposure fusion with lux on a serial
shot with constant Ev, you should get the noise reduction as well,
because the images will simply be averaged where they fit.
Usually the noise is most problematic in dark areas, so an AEB with
different exposures - including at least one bright one which shows the
dark areas well - is even better for noise reduction. If you don't have
bright content, just leave the dark shot(s) from the bracket out.
