(Early Access) Assisted Culling (LrClassic)

I love the idea of assisted culling but it has never ever worked on my system. I go to the catalog settings and uncheck “scan all photos in catalog” then go to the job queue at the top right of the library and click the triangle to see what’s going on and Culling is Paused. I unpause it and it starts scanning my entire catalog. I go back to the Catalog Settings and the “scan all photos in catalog” has reverted to checked. The culling also wildly misses the analysis. It’s not even close. Very sharp images (Nikon Z8 with Z 70-200mm) are rejected. 

Restart and repeat does not change behavior.

This would work better if it was tied into the normal pick/reject flagging. You could then review the choices and manually pick or reject individual photos. An apply, Okay, and cancel buttons would be helpful aswell.

Similar to the selection tools in Photoshop, it would be nice to re-run with different settings to add or subtract from the chosen images. An AI interface where you could define your own selection criteria would be great too.

How do I use this on the selected images only? It is extremely slow and I have no use for it with 2000+ wildlife pics all at once, taken in bursts to fight camera shake in low light.

After a number of somewhat successful  “cycles” with asst culling, it now shows the number of stacks and unstack photos that will be displayed using visual similarity but after executing it does not display any stacks. I have not tried shutting it off and restarting - that will be next step.

I’m using Release 15.3 on Mac.

Below is picture folder contents with 8 photos. Two are very similar professional portrait copies.  Three appear to be the same photo with different names.

Results of culling DO NOT DISPLAY A NUMBER ANYWHERE

If I didn’t know that the photo with van with adult&child standing beside it, I would not know where to look and decide which photos to purge.  This worked yesterday!

Very slow, both to perform the culling filter and then especially to cycle through the images afterwards to confirm you’re happy with the choices.

If you have thousands of photos and are happy to trust the AI then I’m sure it’s quicker, but if you want to retain any element of manual control then it’s probably not worthwhile.

very slow and inaccurate

It is very slow. It seems to stop altogether after analyzing less than 1000, yet it holds onto memory and seems to slow Lightroom Classic unless you pause it.  I have tried to use it for several weeks and it just stops. I have over 16,000 photos cataloged, it gets to 771 and stops. I am trying to find out of focus. I set focus score to 80. It says only 64 are out of focus (I guess that is good except I doubt it is accurate based on my eyeballing the photos it culls). But out of 64, it shows a rejection count of only 2 unless that is the count of images that have the rejection flag turned on. That does not make sense to me.  I have tried accessing help. If this is going to work it needs to be able to be able to restart where it left off and move faster. I have 32 gb memory of my dedicated Windows PC. Task Manager shows my system is loafing with less than 10% to 15% cpu utilization and about 50% memory utilization.  Again, this PC is dedicated to photos and Adobe. No other apps running. 

Is there a way to turn it off: it always causes my LrC to crash out. I have c. 80,000 photos and don’t need this to happen every single time I use LrC.

When you support bird photography better, I would like an option to reject photos where the subject (the bird) isn’t completely in the frame. If a wing or feet are clipped, reject it.

Cool. But can you add a feature for styles or like for example I do fashion shots and it would be great to have it select best poses. Or custom train model so the user can train it to their workflow or style. Some times it work but some times I did my shots so well that it don't do anything like just one picture was rejected. And the settings for sharpness its too extreme needs an in between  (light medium hard).  Other thing that would be great is the repetitive cropping specially for dynamic shots. Make he ai detect where the subject is then evaluate and leave margins as the user specified use golden ratio and finish the batch.
