Terrible amount of artifacts after stitching

[Christian Gamio]

I´m getting an terrible amount of artifacts after stitching while using PTGui on "2 store" panoramas - specially on flat areas. Considering the price of PT Gui it´s unacceptable!

And this is not even the worst example - but it happens like this to often and it´s annoying.

Hi Christian,

Judging from your image, this may happen if the images are pre-processed
before feeding them to PTGui and the brightness of neighboring images is
inconsistent.

You can see if that's the case, by switching the Panorama Editor to
'unblended' mode. Ideally you would still see a reasonably good
panorama, with not too much variation in brightness between neighboring
images. The blender will smoothen out those minor differences.

If you preprocessed your images using tone mapping or applied strong
shadow/highlight correction, those images may have very inconsistent
brightness. The blender will have a tough job correcting this, and some
artifacts may remain.

The recommended approach, especially with PTGui Pro 13, is to stitch
your DNG files directly in PTGui. Then do any adjustments after stitching.

Alternatively, disabling 'optimum seams' may help sometimes. This causes
the seams to move further away from each other, making the blending
artifacts less noticeable.

Kind regards,

Hi Joost, thanks for the kind replay. My workflow starts with creating HDRs out of the Tiffs out of the DNGs, but no change to exposure, white balance etc. 

The thing is, other pano software like panorama studio is not having this problem (they have others :-P )

I´ll try your sugestions

Thanks a lot

Christian

You can try to use the Multiband Blender and switch off Optimum Seams to
more or less mimic the blending of Panorama Studio. But this might give
you ghosting in some places, if the images don't overlap perfectly.

I guess the other panorama software is using Multiband blending? This
is an option in PTGui as well.

If I understand correctly, you're tone mapping the images prior to
stitching. This actually makes extreme adjustments to the exposure
levels. Have you tried switching the panorama editor to Unblended mode?
This might give some insight.

Kind regards,
