Hi,

Lightroom ignores already imported images, even though I select "New Photos" and check "Don't Import Suspected Duplicates".

My catalog:



Import dialog, same images, same names...:

Try resetting your LR Preferences file as outlined at the below link. I suggest moving the Preferences file to the desktop so you can restore it if of no help. Restart LR and it will build a new Preferences file with default settings. See if the issue is fixed.

Do  you Rename the photos when you import them? It's ESSENTIAL, but after looking at your imported shots I see you don't. Once the camera runs out of filenames (at 99,999), it will go back to 0001 (or whatever), which you will already HAVE in your catalog, and now it will have 2 images with the same name (not good!) Try "Clientname2020-1" of some variation like "Shootname2020-1".

Could this be why? I never have this problem, because I always reformat cards after a shoot, so it's always New Images.

Nope, I don’t rename them ;-)

As you can see (well it’s not that clear, granted) the filenames are identical : DSC05920.ARW for the first one, for example.

And I don’t think having the same file name will ben an issue, as Insuppose LR is also looking at exifs to find out if images are similar. There would be way too much false positives without checking images. I’m sure there are hundreds of “Image001.dng” or similar standard names in many libraries ;-)


Formatting cards doesn’t change a thing regarding file names, though... it shouldn’t have any impact at all. (I’m not saying it’s not a good habit, though! I frequently do the same. In my particular case, the images already imported were from mobile, but I couldn’t import everything on mobile)

I am not having this problem with Lr 9.1 on Windows 10.

I never rename my files on import nor any other time and have 16 years of images stored in folders by year. I reset my filename numbering in my camera at the beginning of each year (I don't take thousands of photos a year), so my catalogue has many identical filenames in it without any issues.

There is more to identifying a suspected duplicate image than the filename, such as Exif data, file dates, file sizes.

I would try Todd's suggestion.

I notice in the Destination section you do not have anything checked as to Where you want LR to Copy those images to. Have you tried selecting a location in the Destination section?

@Anthony: I'm on MacOS

@Just Shot Me: It's because the target drive is collapsed. I have the habit to choose the import location by "Import to this folder" rather than in the import dialog ;-)

Hah! New clue!! It does it only from images imported through sync process, not imported from the SD card.

... Yet another sync bug... :-( :-( :-(

Imported through sync how long ago? There were some changes in this regard a little while ago. It also missed Import from Catalog photos for years too, but that's fixed.

A week or two ago, not much longer.

This might be a clue... Appears on all synced images, not on imported through SD...

Hey Antoine, I hear what you're saying, but you've been around here long enough to understand that these problems need to be reproducible in order to go anywhere.

Rikk did more testing than me but for what it's worth, I couldn't replicate the behavior either.  That's not to say you're not experiencing it.  Just that I can't replicate it.

Have you tried it with different file types, a different catalog, did you reset your preferences, etc?

Half the problems on this forum have nothing to do with "Adobe has screwed up", it's "your OS is messed up" and that's why it doesn't work. Get an IT GUY! Then you can talk about Adobe.

Thank you Carlos. It's very helpful and obviously taking into account the clean install I've performed yesterday. Also having studied my up to date Linkedin page to know wether or not I'm an "IT GUY" was of great help. Ayway...

@Tom: good idea to try with another format, it helped:
The bug happens:
  • With Sony ARW files
  • Sony JPEG
The bug does not happens:
  • With DxO Raw files
  • HEIC on Sony's SD card
I'll continue investigation with other files, but it's really strange!

Antoine you didn't have to do that, I could have TOLD you you're not an IT guy! Your sarcasm is unappreciated, just trying to be helpful (after 25 years of IT experience). End of line.

Damnit!!

Sure, no problem :) It's exactly what I've done in previous example (whereas I hadn't formatted the card before).Here is the zip file:

Sorry it's an uncompressed raw, so a little heavy ^^

Ok. With this file, I can make it fail on Lightroom Classic but only from an SD card - It works as expected with the same file on a CF Card. 

Interestingly Lightroom Desktop recognizes it as a duplicate in both cases. 

Do I have your permission to include the file on the bug report?

Thanks Rikk! That’s excellent news! :) 

Of course you can include the file in the bug report. :)
