OK, and there is no way to not link featureless images automatically, while still linking featured ones?

What if I can't use hard links between bracket layers?

Why could you not use hard links within stacks?

No. In a perfect world, you would not have do that trick. But, as the computed focal value is not what it should be with the default settings, you have to remove that links to avoid focal divergence.
We plan to study why.

Regards,
Thomas

When I'm using my larger lenses, and particularly in high winds, there tends to be small motions between brackets that cause minute but noticable mis-alignments between images. It won't happen every time, and if I'm going to have to use hard links between stack elements I'll do everything I can to prevent it from ever happening - which may actually include not shooting some panoramas.
I guess I could always merge to 32 bit HDR files elsewhere and then stitch these, which I'm planning on trying, but am having some issues and need to work out if those are my fault before I start a thread on these.

Are there any guides anywhere that would help me understand what you mean there Thomas? I'm actually quite interested in the algorithms that you use and things as well :)

Hello Martin,

Analyzing your images a little more enables us to find an issue (#1800). We already have a fix for that, and it makes your panorama to be stitched perfectly with automatic detection. This fix will be included in the coming version.

Thanks,
Thomas

OK, that's great - do you know when that version will be released?
