P: Search for Duplicate Photos

Has anyone tried third party desktop duplicate finders using visual processing? I saw one advertised but thought it might be sketchy. I have over 108K photos and am not done integrating old iPhotos/Photos/Aperture and other libraries spaning 25 years. Much of my EXIM or other Metadata is lost, incomplete and/or incorrect so most duplicate finders don't really work. Further, it would be helpful to find bursts and choose the best etc.

I'm away from my desktop right now, but if you click on the Edit button (sliders) top right, you'll see Versions at the bottom of the Edit pane. HTH

The Versions button is at the bottom of the Edit sliders panel and it's great at its job! It's just no good at finding real duplicates!

Hi Si Keeling.

Can you please provide some screenshots as I don't see any Versions buttons or controls. Hope you are talking about the CC, not the Classic Lightroom. 

Thanks

It successfully found duplicates of a file I imported. So it worked for me, YMMV

@Si Keeling for the sake of clarity, those aren't real duplicates. They're just different sets of edits of the same photos, so you can experiment without needing to create duplicates.

I think I found a way. Use the Versions feature (bottom right of the workspace area). It brings up duplicates of the same image. Hope this helps!

I to NEED this feature! Going through old photoes with duplicates which appears for different reasons (previous migrations and merges of hard drives). Would be nice if the feature not only found exact duplicates but also similar photos, different resolutions, different versions (BW vs. Colour) etc. 

Adobe - Please, please , please give us a duplicate finder feature for Lightroom CC. I find it difficult/impossible to believe that we have yet to see this feature on what appears to be turning into your flagship photo manager. Anyone migrating their photos is likely to encounter this problem for one reason or another.  Your facial recognition feature is beyond awesome. It's been two years...  Clearly this should not be such a big ask?

I am slowly importing, and loading older images from multiple sources.

This is leading to duplicate images. Previously with Classic I used external tools or plugins to find duplicate images. The best tools used either a pixel hash excluding a border amount (very fast, but will miss some changes to the image), or used interest point (very slow, but more accurate).

I would like to see such a framework added to Lr; or a plugin architecture allowing for such a third party tool to be developed.

Note: would likely need configurable settings if duplicates found to ignore if select metadata does not match (such as root filename and capture time) to account for high speed capture sequences.
