If the files have different file names or different metadata? For example,they might have different dates attached? If there are multiple different metadata differences, Lightroom won't recognize the files as duplicates (even if the image data is exactly the same).
Would you please check if you have such images.
I've reviewed the import dates in Lightroom and there appears to be an error:
For example, when I hover over the photo that is found during import, it states my photo is from 14 years ago! Obviously, this is not the case and is likely why Lightroom insists on importing photos that are already part of my library. When I choose to import this photo and review the metadata, the same photo shows the correct date.
I've attached screen shots of the date info during and after import.
From import dialog and date displayed:
From imported photo and metadata showing correct date.
Do you have a solution to this issue or another way of not importing duplicates?
Any resolution to this question? Thank you!
This EXACT problem constantly happens to me as well! I've spent many hours cleaning up duplicates, only to have them reappear. It would be nice if Adobe could the issue one and for all.
While importing make sure you are not using any preset, also make sure that your LR is up to date.
Hello, I have Exactely the same issue since I upgraded to LR 6.10
It was working fine for years... It never imported duplicates, but after a lightroom upgrade, it stoped identifying duplicates and want to import all pictures in the iphone, but also on any other camera
Sarika is correct! I import from the iPhone and change the names or add metadata in import and thus, the next time I do this, LR thinks ‘duplicates’ are not duplicates due to this difference. It can’t do otherwise! IF you import the iphone images and do absolutely nothing to alter them, the duplicate command should work. But few do this; we add information upon import or alter the files. Frustrating but I don’t know any kind of workaround and this has been an issue for me since day one. So not unexpected IMHO.
Hello. I too have noticed a change where now Lightroom 6 duplicate imports from Apple iPhones (iOS). The "Don't Import Suspected Duplicates" worked well for years. There are no Lightroom presets applied or other actions in place. Not sure if this issued started with an update to iOS 10.x or Adobe Lightroom 6.x? Still looking for a resolution to this...
Maybe the issue started when iOS introduced the face finding feature:
