Raw photos sent from LrC to PS do not go to ACR.

Thanks for the info D Fosse.  That was very clear.  I learn something new everyday and that is a good thing.

This may seem confusing because a lot of the Lightroom > Photoshop interactions are handled by background scripts.

An open file doesn't have a file format. Fila formats are storage containers. So when you save the file, it is encoded into a file format. This is where the script comes in, by telling Photoshop to save it as a TIFF. Or PSD, as the case may be.

As long as it's open, the file is just an image sitting in RAM. The title bar tells where the file is coming from, not where it's going, since that is normally unknown at this point.

Thanks Lumigraphics.  I didn't realize the file name didn't change to the tiff format until it returned to LR from PS.  For some reason I thought it showed up as a tiff when it went to PS.  Technology is killing me.  Appreciate you help.

Your files do not go to Photoshop as CR3, they are demosaiced and sent as TIFF or PSD format.

BrettN, since the upgrade LrC sends my CR3 raw files to PS as CR3 files instead of tiffs. Preferences are set in LrC to send files to PS at a tiff and that is why I thought I should be able to use the denoise feature in PS.  I have been using LrC for years and use it for most everything except for a few of the things PS does better (as you noted).  Not sure why my files are now going to PS as raw files but they do.  Thanks for the response.

Thanks Lumigraphics.  I knew the feature I wanted wasn't in LR but I did think I could send a raw file from LR to PS and run denoise from ACR there.  Well, it will eventually come out in LrC so I will just have to wait.  Thanks again, Susan

You cannot run your workflow the way you want. The new denoise is a technology preview and only available in ACR, NOT Lightroom. So you have a choice- Lightroom and the older Denoise, or Bridge/Photoshop/ACR and the new (essentially a beta) noise reduction, without Lightroom.

Right now its one or the other.

Lightroom Classic still sends raw images to Photoshop as TIFF (by default, you can change it to PSD in Preferences > External Editing). Lightroom's Develop module has the exact same toolset as the Camera Raw plug-in in Photoshop (they are essentially the same thing). The general workflow is to complete all Raw edits in Lightroom and then send it to Photoshop to handle all the edits that only PS can do. When you save the file in PS, the TIFF (or PSD) gets imported back into LR and gets stacked with your original raw file.

If you are skipping the editing capabilities in Lightroom, using Brige for organization in your workflow may make more sense. There, you are working directly with your files off the hard drive and would open them directly into PS from there, thus having to process them through Camera Raw first before proceeding to the regular editing environment of PS.

Editing raw files in Photoshop means that the edits you perform in the Camera Raw plug-in will not end up back in Lightroom. This means you won't see the changes you've made without manually import them.

Thank you.  Guess I didn't make my self clear.  I know that LrC doesn't have all the functions of ACR in PS, that is why I would like to send my raw files directly from LrC to PS to make use of those functions.  However, when I do that, the raw file shows up in PS but not ACR and when I send it to ACR the new denoise function is not available.  I can us PS's ACR function if I open a photo directly into PS bypassing LrC completely.  This is annoying as it means I have to send the photo back to its original folder after using ACR in PS and then import it into LrC.  Too many steps.  All I want is to be able to send a raw file from LrC to PS and have that raw file open in Camera Raw.
