LR 8.3.1 Photo Merge > Panorama (Cylindrical) does a bad job of blending this panorama:



But Edit In > Merge To Panorama In Photoshop (Reposition) does a fine job:



The panoramas and original photos can be downloaded from here:

John, I am seeing the same merge you are.  Tried Classic, Desktop and Camera Raw and they all yield the same result. I will forward this to the Camera Raw team.  Can you leave your dropbox files active for us?

Yup, I'll leave them there until the problem is addressed.

Another example (similar scene, similar haze), in case it helps:

John,

We got to the bottom this.  This camera has a built in ND filter that can be automatically enabled. Camera Raw, and the Lightroom Desktop Clients are thrown by this. Photoshop treats the constituent files as rendered instead of as raw so that's why it doesn't exhibit the same issue. We have a fix in process for an upcoming release for CR and LrD, LrClassic.

Excellent, thanks. I believe the ND filter is on by default.

I'd be curious to know what camera this was shot with, John(that has a built-in ND filter)!

It's a Sony RX100 V.

I had the same exact issue with panorama sets shot with a Canon G9X MKII. It has a -3 EV ND filter that kicks in when the shutter speed is near maximum. I use Lens Tagger to change the shutter speed by 8x.

EDIT: I forgot to add if Adobe fixes this you'll need return these image files back to their original shutter speed. I suggest keywording any files you change with 'ND 8x Shutter Speed Corrected' or something similar. That way you can easily find and correct them in the future.

Todd, Want to send me a couple of files with your Canon with the ND Filter engaged and we will verify that we are handling that correctly?

Thanks Rikk. Here is a panorama shot with four files. The IMG_2404.CR2 file has the 3.0 ND filter applied in-camera and the other three do not. The shutter speed shows as 1/250, which should be 1/2000 without the ND filter. Using LensTagger to change the shutter speed to 1/2000 corrects the issue.

Please let me know if you need any other information.
