P:(Masking) Make the mask available in Photoshop?

I often need the masks that I created in Lightroom when I edit the same photo in Photoshop. Ideally I could also create named masks in a PSD file and when daverd back to Lightroom I can use tthe masks as well. This feature , obviously would not be available with JPEGs but could be a a part of the PSD format. 

This is not what you are asking, but just my thoughts- why do you not do the masking in Photoshop, if you know you want 'masking'.?

It has the same 'Select Subject / sky' functions, and you can brush on masks to add-to or erase masks in adjustment layers.

Also Luminosity masks can be very useful as is Luminance masking in LrC.

ok, but ACR is basically the same thing as LRC, I'd like to open the selection in PS because I need to do things I can't do in LRC. Being able to use the masked area as a selection in PS would be very helpful. 

There's a roundabout way of converting a LR mask to a PS mask:

1. In PS, make a white TIFF the same pixel dimensions as the photo, and import that TIFF into LR.

2. Use the Copy Settings plugin to copy the mask from the photo to the white TIFF, using the option Original Sky And Subject Masks.

3. In the TIFF, select the mask and set the mask's Exposure = -4.

4. Use the Tone Curve to adjust the black point so the mask is mostly black:

5. Edit the photo and TIFF in PS, and copy/paste the TIFF into the layer mask of the desired layer of the photo.

That's a lot of steps, which could be mostly automated in the Copy Settings plugin. But Rob_Cullen's suggestion seems more useful.

Not possible  as a mask on a 'standard' layer, but-

From Lr-Classic: Open in Photoshop as a Smart Object.

The Masking remains available in Photoshop (the CR UI)  if you [Double-click] the Smart Object badge on the Layer which re-opens the image in ACR- with the Masking.

Is there any way to convert an image mask created in LRC into a selection of that area for use in PS ??

It would be nice not to have to make the selection again in PS if you already have the area masked off in LRC. 

The new Subject/Sky masing in CR is MUCH better than the Photoshop internal versions. Plus, I can make masks in LR, make adjustments there (because it's much easier), then do any PS work with the mask already made, coming in from LR with LR edits.

As to below msg, sorry, I thought I put this in Ideas.

Can you give a more detailed example of why you'd like to access the Sky and Subject mask as separate layers when you open in Photoshop?  The better Adobe understands why you want a feature and how you might use it rather than just what you want, the more likely they'll consider it.

(And you do know that Photoshop has Select > Subject and Select > Sky?)

I am currently working on a photogrammetry project and need to mask 750+ photos. I saw a demonstration of the "Select Subject" masking available in Adobe Lightroom and was very impressed. Question is, can one export the mask?

In addition, I'm hoping to automate this process as much as possible. Is scripting available with Adobe Lightroom? Or will I have to make my own plug-in to achieve such a thing?

I'm hoping to:

- load in images

- apply "Select Subject" to images

- export masks for images
