P: (Masking) AI Mask copy/paste: separate the mask-outline from the mask-effect settings

Explorer ,
May 11, 2023 May 11, 2023

I'm now using AI Masks (especially the SUBJECT mask) a *ton*... they are great!   In particular, I'm using these for sports photography where I'm shooting lots of bursts in the sun .. and need to dim the bakcground while making the subject brighter.

 

When you use these a ton, it's very expensive for the AI to have to re-evaluate the edges of the mask ... it takes time and battery ... but there's lots of situations where you want to adjust the brightness/white-balance of the subject and then copy/paste it to a whole bunch of other photos... without needing to re-evaluate the mask edges.

 

THE IDEA:  on copy/paste of develop settings, separate the mask edges from the mask settings, like this:

[x]  Masking
       [x]  Mask 1 - settings (brightness, etc.)

       [  ]  Mask 1 - update AI-derived edges

       [x]  Mask 2 (blue sky) - settings (brightness, etc.)
       [  ]  Mask 2 (blue sky) - update AI-derived edges

 

With the options as above, I could adjust the brightness/contrast of hte first image in a burst and then just paste the change *without waiting for the AI to re-evaluate the mask edges*.  Much faster!

While waiting for Adobe to implement this, you could use the Original AI Masks option of the Copy Settings plugin:

When making timelapse movies and editing multipe pictures with the same shot with the same settings, it would be very helpful of the AI mask isn't recomputed when copying settings from one image to others.

 

I ususally shoot 100-500 images in a series with the same camera settings and apply my edits to the first image. I then copy these settings and apply them to the rest of the batch to get the same edits applied to the entire batch. But when using the Sky masking tool (Or any other AI mask), Lightroom wants to recompute the mask for every image, resulting in unique image masks on every picture. This means I can not apply settings across the entire batch, when using the Sky selection tool.

Therefore it would be extremely helpful if I could either convert the AI selection, to a simple NON-AI mask OR if it was possible to choose in the "Copy Settings" panel if I want to copy the masking method (AI) or if I simply want to copy the selection mask. If this is not possible, the AI filters (Sky, Subject, Background or People) or  can not be used at all for batch editing timelapse photography.

I made a long timelapse with a many photos.

Now when I copy settings Lightroom apply AI mask to every single photo every time. But this is timelapse and the camera didn't move.

So I want to apply the mask "as is" without new calculation.

 

Is it possible?

No. As far as I know it isn't possible.

I often create a mask and and inverted mask each with different settings on an image and then copy/paste that to multiple other images. Lightroom often masks the wrong area in one or the other mask in the pasted image, Sometimes I can adjust a mask with add/subtract submasks or deleting a submask to get what I want, but often it's easy to create a new mask, but that requires readjusting the sliders to what I want. It woudl save a lot of time to be able to copy one mask and paste just the settings from it into another mask in the same image. Such an option would also help in senarios where someone doesn't want an AI mask recomputed when pasting  such as requested in https://community.adobe.com/t5/lightroom-classic-ideas/p-masking-ai-mask-copy-paste-separate-the-mas.... In that request the desire was paste settings between images, while my reqyest is paste between masks in an image.

Thanks, John.

As an aside, when I tried to find already posted ideas (such as the one you identified) in the 'Ideas' tab of Lightroom Classic and entering "copy paste mask" in the search field containing the hint 'Find your answer or post to this community', 139 results were returned. The results were in many different Communities such as "In Discussions", "In Ideas", 'In Bugs", etc. Is there a trick to filter the results to "Ideas" only so I don't need to slog through entries that are not relevant and find the one you did to which I could add rather than create a new idea entry?

This forum (provided by a third-party service to Adobe) is mediocre at best. You would think that limiting searches to a particular section (Ideas, Bugs, Discussions) would be quite useful...

 

The functionality is there, just not exposed in the UI. Long ago I reverse-engineered these links to search just Ideas and Bugs (copy and paste them into your browser and bookmark them):

Thank you, John. These links work well.
