This error message appear when using HDR mode on Lightroom 6 with 3 photos.
What's happened, any idea ?
Thanks for support ^^
Can you supply a screen shot of the three images you are trying to merge?
Or better yet, upload the three photos to www.dropbox.com and post a public share link, here.
This happens to me when by accident I selected an extra image that doesn't belong in the series. Make sure you look carefully at your selection.
