Lightroom Classic 8.4: Merge to panorama not working

I have created a number of panoramas using Lightroom Classic in the past, some with as many as 24 images. I just tried to create one last night using 8 images using Lightroom Classic 8.4, and it failed miserably. Admittedly, the images didn't align as well as they should have. However, Photoshop was able to create the panorama, and if I opened the images in Bridge then Camera Raw would create the panorama as well. Is anyone else experiencing the same problem? I haven't tried doing a panorama for a while. But Lightroom has never let me down in the past. This was quite a surprise.

I would not jump to any conclusions because one panorama failed.

Okay, I agree. Two different panoramas failed in Lightroom last night, both of them succeeded in Photoshop. Maybe that's just a coincidence. However, Classic has consistently completed my panoramas in the past regardless of how poorly the images matched or how many images were used. It just seems that it's not as reliable as it has been in the past.

Best way to determine what's wrong is to upload a minimum number of the panorama files in the set that exhibit the issue for examination.

Are you using 10.14.6 Mac OS version?

No, I'm using Windows 10. I'm embarrassed to share these images because it was really a poor alignment for a panorama and not a very good image at all. But they haven't failed in the past when using Classic. But since Todd suggested it, I think I have provided a link to a dropbox folder where the images can be found. Haven't done this for a long time.

Jim, as you mention the alignment across the set is pretty bad and it fails Merge to Panorama on my Windows 10 system with LR 8.4. However, using just three image files DSC_3393.dng, DSC_3394.dng, and DSC_3397.dng creates a panorama image file with very good alignment same as PS Merge to Panorama.

PS's stitching algorithms are different than LR's and more forgiving of alignment issues. In short this appears to be due to shooting alignment and not a LR issue....at least with this set.

LR Merge to Panorama using DSC_3393,_3394,_3397-Pano.dng files



PS Merge to Panorama using all six DNG files

Okay, thanks, I will give it a try. I realize the alignment wasn't good. It just seems that Lightroom used to be a little more forgiving. I guess I'll have to improve my panorama skills.

Added later: as you indicated, those three images merge just fine in Classic. I definitely could use a better tripod, for sure. Thanks for the heads up.

Now this is strange. I went back and tried creating the panorama again using all six dng files and this time it worked. Nothing different was done! It is slightly different than using the three image files (upward curvature on left side), but otherwise no issues. I tried it two more times with no issues....go figure!

I downloaded the six images, imported and stacked them, then selected merge to panorama. Lr 8.4 classic had no problem merging all six, but it did first ask if the set was an HDR exposure bracket. Also, my result using the six images didn't exhibit any upward curve on the left side as seen in Todd's result, but I selected Auto Crop. Tried all three projections and all worked (and no upward curve on the left with Auto Crop). I did try setting Boundary Warp to 100 with Auto Crop off and the Spherical projection exhibited a slight upward curve on the left side, but doesn't appear to be as prominent as your Todd. This one is cylindrical with Auto Crop set.

Getting even stranger??

So, had to try on my 15inch MACBook PRO Retina 1015, LR classic 8.4, MAC OS 10.14.6. Went for a straight PANO, no HDR in the mix, 11 frames, well overlapped, on tripod, level. Getting the Preview was Ok time wise, if I was running this on my 4K external, the merge is slow, very slow (note LR reports GPU as capable of Basic ).


Note, 4K display, scaled down to 2560x1440 (not same as resolution of 2560x1440)


Shame on me, will need to retry and time.


If I disconnect the 4K external monitor, and just use the Laptops screen (2880 x 1800) the merge is quick, less than a minute.


Suspect on a MAC, issue relates to just how many pixels are being created.

Note: This notebook is my travel computer, it is not normally connected to the external monitor for post processing in the field., so Photo Merges connected to a 4K monitor is not the norm.
