After 10 years of making panoramas in Hugin, I see that the most
of panoramas look better (more naturally) without exposure
correction.
Especially the sky and night scenes.
I suggest adding two *optional* steps in the Assistant preferences:
Correct exposures, correct colors,
without entering the Panorama editor to Reset.
I see the opposite. For me the panoramas become significant better
with photometric corrections.
I generally see that, too, although it depends on the source images. But
I generally try to do exposure correction (if any) in the source images.
I think it avoids the occasional situation where Hugin maybe gets
confused when the images have a wide range of exposures and/or color
temperatures?
There's one situation where Abrimaal's idea makes sense for me: when
using 16-bit HDR source images. I don't do any exposure corrections in
the source images, just take them as the camera produced them. Then I
use Hugin to stitch the images into an EXR panorama and process that in
Luminance HDR. So I don't need or want exposure correction for the
source images.
Now, how does this connect with the Assistant? I usually follow a manual
process (align, clean control points, next step of aligning, clean, etc)
for aligning images. In some cases, I've been unable to get an aligned
panorama out of the set that way. But in many of those cases, starting
from scratch using the Assistant produces a nicely-aligned image - only
with the photometric corrections I don't want.
While that can be cleared in Hugin, it might be nice to have an option
to turn it off in the first place? Or is that something that could be
done in a modified Assistant script?
