P: Synchronize folder does not import new images unless show import dialog is active

I can't find the relevant forum messages, but I recall that LR considers two photos "duplicates" if they have the same filename, date (not sure if that's OS file creation date or capture date recorded in the metadata), and size. Do the pairs of photos that are falsely considered duplicates meet those criteria?

This worked for me but seems an unnecessary workaround that wasn't needed before

Somewhere in Adobe's help files I once read that Lightroom does not automatically recognize duplicate photos. But in this case it sure looks as if it is trying to -- and botching the job.

If the files are in separate directories Lr should at least offer the option to import them anyhow,

Version 6.1.1 has the same bug: Given two directories of almost identical photos (stereo pairs) having the same file names, it claims that some of the photos in the second directory have already been imported and refuses to import them. Whichever directory I import first gets imported correctly.

So this bug is not in the new import dialog but is something more fundamental.

The workaround I am now using is separate catalogs for the left and right
photos.

Thanks, John and Victoria. Reverting to 6.1.1, will report if it works.

You can revert back to CC 2015.1.1 / 6.1.1, the last stable release (with the old Import): http://www.lightroomqueen.com/how-do-.... That way, you can continue to use your current catalog and won't lose any edits.

New installation of Lr cc on a Windows 10 gaming laptop. I have about 475 stereo pairs, the left images in one folder and the right ones in the other. The file names in the 2 folders are the same. Importing either folder (into a new catalog) seems to work; but when I try to import the other, about 40 files are flagged as "already imported".

I have not found a way to force these files to be imported anyhow. When I try to synchronize the catalog folder, Lr first reports the missing files but finally rejects them with the same message. "It appears that this photo has already been imported".

Falling back to Lr 5 until you fix this stupid bug.

I think this is instance of the more general bug, in which LR does not sync with subfolders unless the option Show Import Dialog is checked.

Using "Sync Folder" in the Folder panel does not import files in NEW subdirectories. New means the folder is not yet in the panel, just new on disk. When you sync the dialog tells me, that there are new files, but does not import them. When I add the folder with the right name in the panel, it works.

It doesn't matter if I have "show import dialog before importing" selected or not.
