Syncronise says there are photos to import, but then does not show any.

Hi @Crystal Visionary 

Hope you are doing good!

Try unchecking "Show New Photos Only" in the import dialog. Also, ensure the files aren't already in the catalog and check for hidden or unsupported formats. If the issue persists, try resetting Lightroom preferences.

Thankyou!

I think the explanation for this is as follows. If you use the 'Synchronize Folder' menu, Lightroom will initially just compare the actual contents of the folder with what it has in the catalog for that folder. If it sees images it does not have in the catalog for that folder, then it will say it needs to import them. However, when you tell Lightroom to go ahead with the import, it will check the images against the entire catalog. So if you already imported those images by making a copy in another folder, then Lightroom discovers it does not have to import these images after all. So search for them like @dj_paige said, but remember you could also have renamed them on import...

This happens becuase the photos you want to synchronize are already in the catalog. So no need to synchronize. You can find the photos in your catalog via following ALL 4 of these steps, in order:

1. In LrC, click on All Photographs (left side of the Library module)
2. Turn off filters (ctrl-L once or twice)
3. Expand all stacks (Photo->Stacking->Expand All Stacks)
4. Use the filter bar to search for one of the photos by file name.
