I am using macOS Sierra and MacBook Pro (Retina, 15-inch, Mid 2015). My latest lightroom CC (Build 1106920) have problem in merging photos I took with shifted 17mm TS lens on a very sturdy tripod. I frequently did this and never had any problem before. Please fix this, as I need to deliver these stitched photos to my client.

Can you upload the problem files somewhere and post the link please, as the engineers will need the files to reproduce the problem.

Hi Victoria,

Thank you for the quick response.

Later after posting this, I noticed that the stitching errors only happened to files from shooting spot with wooden flooring. When I worked on the files from spot with solid floor, I didn't have the stitching problem.

Then I asked the location project contractor, and I found out that they put soft underlayer beneath the wooden floor for construction purpose, and the underlayer and the wooden layer were not quite firmly attached at the moment. Thus introduced some movement to my tripod and camera. 

So, I almost sure the problem is not on Lightroom side. But still I upload the files, and if you and the engineers team have time to check this out just to make sure, it will be very helpful to know the outcome from your side. You can find the files in https://www.dropbox.com/sh/5mc5ghgdbwc6g6n/AADfjRbT9u6RDA6cMitlPxu8a?dl=0

I apologize for my misunderstanding.

I've also noticed this in some extremely simple panoramas such as of a city scene even with just 3 photos. Depending on the perspective option the stitching error either is on the left side of the scene or the right. So LR knows how to stitch both sides correctly, but just can't do both correctly at the same time.
My stitching error looks exactly the same above.

I've taken to fixing in Photoshop but about to give up on LR as I just can't trust it.

Hi Luis

I've just downloaded the pictures but they're definitely not stitchable because they're not overlapping or even side by side. Maybe you sent the wrong ones?



I would expect LR to be able to compensate for slight movement in the floor, as it regularly manages to merge ones even shot handheld.

In fact, the previous one worked on Perspective setting too.

Yes, I shot raw and stitched them in raw too. And I used perspective setting. But no success for me. 


This is Set2_ stitching preview in perspective.

Ok, we'll need the raw files then. I can't reproduce that on the JPEGs.

I uploaded the raw files, and two DNGs from HDR merge of each set of 5 raws.
I found out that if I stitched the DNGs, I got the error. But if I stitched two raws (ie. IMG_3762.CR2 and IMG_3767.CR2), it came out okay. Hope you can reproduce this problem.

Thank you!

Ah ok, merging panos from a merged HDR is a different ballgame. It looks like there's a slight shift in pixels when merging 3767. Running the HDR merge again with auto align disabled and then merging that to pano seems to come out ok (although I haven't checked it in great details.)
