You need to provide a little more information such as are you trying to import RAW files or RAW+JPG because when you import to LR it wont import suspected duplicates if "Don't Import Suspected Duplicates" is ticked in tht import dialog.
Or in the case of RAW+JPG LR will not import the JPG files if "Treat JPEG files next to raw files as separate photos" is NOT ticked on the General page of the preferences.
The files are all RAW. I suspect that the problem might be related to duplicates, but those pictures don't exist in the catalog. I can't find them in a search, and LR reports 0 pictures for that directory.
since you are shooting RAW, please state the camera and version of Lightroom.
You have the symptoms of the situation where the photos have been previously imported into Lightroom, and perhaps accidentally imported into a different directory. So, you need to search Lightroom for one of these photos by file name. In order to do the search, you must first do ALL of these three things before searching:
- go to the Catalog Panel on the left, click on All Photographs
- Expand all stacks
- Turn off all filters (Ctrl/Cmd-L once or twice)
That was indeed the problem, thanks for the tip.
