I merged 15 NEF files successfully but the image is very very bad. I'm not sure how to describe (but pixelated is a word that come to mind) it so here's a screen shot
And when I export it as a Tiff using these settings.....
This is what I'm left with when I open it in PS
Here's a closer view
What am I doing wrong??
A number of others have reported that issue in this bug report in the official Adobe feedback forum: lightroom merge panorama creates a small image when combining 13cr2 images. Please add your vote and details of your issue to that report, including the exact version of LR you're running (do Help > System Info -- don't rely on memory). Adobe employee Simon Chen said in that topic that LR 6.2 / CC 2015.2 contains a workaround that should avoid this issue.
Best to continue discussion in that thread, where it will be visible to Chen and the others experiencing the problem.
Thank you for your help
