I'm running LR 6.5 on a iMAC. RAF Fuji files which I originally imported from SD card worked on and exported as PSD and then after backing up RAF files on an external HD deleted them from Lightroom. I now want to import some of the RAF files from the HD but LR shows as them as dulled out and says they have already been imported when I hover over the thumbnail. I have not got this problem when importing CR2 Canon files in the same HD and which have been treated exactly the same. Anyone got a clue as to why this might be happening? Thanks, Phil
If Lightroom is reading those files as duplicate then, it shows they are already present in your Lightroom Catalog.
You might want to search by a filename and check if that image is present in your library.
