P: CR/Lr select subject not working properly

[Wian0D45]

I recently upgraded to a new 14" Macbook Pro from an older 2017 13" Macbook Pro for smoother and faster photo editing. I love the new laptop and it performs great, except for the fact that the select subject feature in ACR is not nearly as accurate as on my previous Macbook. I just did a little test to see what the effect would be in Lightroom and there the select subject is just as accurate as before.

Is there a setting that I can change to increase the accuracy or is this a problem that occurs with the latest version of ACR?

P.S. I prefer editing my images with Adobe Bridge and ACR rather that with Lightroom

Rick,

Thanks for your post. You're absolutely right. I unchecked "Open Using Rosetta" and LRC grabbed the subject on the first try.

I noticed the exact same behavior in Photoshop. "Open Using Rosetta" was checked. I unchecked it and the Camera Raw Filter identified and masked the subject immediately.

The question now is whether Rosetta should be checked in Photoshop regardless of the errors found in Camera Raw filter? Or doesn't matter in PS unless using tethered mode?

Thanks,

KW

Thanks for your valued input.

Hi,

I have got Macbook Pro M1 Pro (Silicon) with Lightroom Classic 11.1 and the mask subject tool doesn't work properly. It doesn't select the subject anytime. It selects much more abstract shapes. 

Anyone knows why I can't get good masks with Mask Subject? Could you help me?

I tried reinstall, reboot previously. It's like it can't select the subject never, even with simple backgrounds and chroma key. I attach examples with original images and subject mask selected:

Thanks a lot for everyone

I downloaded one of your images and imported it into LrC 11.1 on MacBook Pro M1 Pro and don't experience the issue you describe/demonstrate. I've attached 3 versions of the mask for yoru first image as an example.

[Dani Gascón]

Oh that's the mask I expected!

And I can see we have the same Macbook and version.  I'm really really confused about it, because I didn't setup any strange adjust. I only click on the Subject Mask and that's what it mask. I attach a video below.

Thanks for the response Ian

[Ian Lyons]

It looks like you've already been using a green-screen and blending the subjects into backgrounds. Are your original layered images from Photoshop? I yes, then try flattening the image before saving, then import the flattened version

[Dani Gascón]

No, I imported the images directly from Finder to Lightroom Classic and the images are .RAW, .DNG or .JPG

[Ian Lyons]

Can you upload one of the original images (ideally the guy with building background) to Dropbox or similar and provide the share link? That would enable us to see if the issue is specific to your setup or the image itself.

[Dani Gascón]

For sure!

This is the original in .DNG: https://www.dropbox.com/s/z8ckxwm11b94owr/IMG_2678.DNG?dl=0

And this one in .JPG: https://www.dropbox.com/s/lek0dlkj8k3w1fg/IMG_2678.jpg?dl=0

[Ian Lyons]

And another of your images with masks working as expected.

Watching your video, it looks like with no mask created you go directly to the desired adjustment brush first. In your case you click on the Select Subject. Seems a bit of a shortcut that might be introducing issues. Might not be what Adobe planned on. This would have been a pre v11 approach.

I could be misreading/watching the video.

Instead, click on the create mask button, Then select the adjustment brush.

In addition to a sample image, please do the menu command Help > System Info and copy/paste the entire contents here. That will show us the exact hardware and software versions you're running.  LR's AI masking uses Apple-provide AI libraries, graphics drivers, and the graphics hardware to run the selection algorithm, and it's certainly possible that your configuration is buggy.

[Dani Gascón]

Sure!

The 'Subject' mask works fine with your originals on my MacBook Pro M1 Pro and Mac mini M1. However, I see from your 'System Info' that you're running LrC in emulation mode (i.e. Rosetta).

'Arquitectura de la aplicación: x64 (emulated)'

When I switch my sytems to emulation mode I get similar behaviour to yourself.  I also tried the 'Sky' mask, which seems to work OK. This suggests that the AI  'Subject' mode is either not compatible with emulation mode or there is a bug in the code that hasn't yet been mentioned / identified here on forum. Given that 'Sky' works, I suspect the latter. Strangely, 'Subject' mask with my own images work fine in both native and emulation mode.

Have you a reason why you neeed to be using emulation mode? If not, then I recommend that you run LrC in native Arm64 mode. This is easy to configure via 'Get Info'. That is, 'Open using Rosetta' should be unchecked as shown in below screesnhot. In the meantime, I'll submit a but report and attach your images.

[Dani Gascón]

Oh Ian! That's it! Now is working perfectly!

Thank you so so much and totally grateful Ian!

Hope you have a nice nice weekend!

Moderators, @Rikk Flohr: Photography,

please merge with the existing bug report about Select Subject/Sky on Rosetta:

https://community.adobe.com/t5/lightroom-classic-bugs/p-cr-lr-select-subject-not-working-properly/id...

[radium567]

This bug is a known behaviour of "Select subject tool" in Camera Raw module under Rosetta-started-application for couple of months already, now up to version 14.4. 
You will ALWAYS get corrupted "Select subject" mask WHEN your hosting application (Bridge, Photoshop. Lightroom) will be launched in Rosetta mode.
If you are launching Camera Raw from Bridge, you are out of luck, Bridge IS STILL NOT Apple silicon native.

When you are starting Camera Raw from Photoshop or Lightroom, make sure you are NOT starting under Rosetta, and everything will be fine.

You might want to start Photoshop in Rosetta mode in case you still want to use legacy Filter/Plugins, which are not Apple silicon optimised, like for example in my case Anthropics Portrait Studio Pro, or Flaming Pear Software Flexify 2.
If you start host application natively, you will not see this legacy plugins anymore in the menus, they will not load. Then - If you start Camera Raw module, your "Select subject mask" will be corrupted.

Photoshop runs natively since March 2021, dear Adobe, could you please finally deliver Apple Silicon native Bridge as well?

Or - at least - fix this "Select subject" bug in Camera Raw called from Rosetta started applications. 

Many of us batch process files with Bridge, without need to import and catalogue everything, and all the edits will be saved in .XMP sidecar files. 

And no, opening files in Photoshop is not a solution, because you have to save copy of your edits in a another heavy separate Photoshop file, if you want to keep non destructive edits like in RAW+XMP tandem.
