Comment 12 for bug 1330047

Roland,
Looking back over this story, it does suggest to me that Hugin isn't the source of your problem.

(1) Camera jpegs stitch OK
(2) TIFF from NEF raw via dcraw stitch OK
(3) Jpeg from NEF via Darktable have problems stitching
(4) TIFF from NEF via Darktable have problems stitching

Have I got all this correct?

If yes, then I think the focus needs to be on Darktable to see if there is something going on there.

Which version of Darktable are you using? Is there a later version available that you can try?

Are your Darktable export settings causing the problem?

Cheers,
Terry
