P: Photoshop 27.10: "Edit in Photoshop" from Lightroom Classic & Lightroom Desktop does not load image with Denoise

If you use the new ‘Render to DNG’ menu, then do realise this: Render to DNG creates a TIFF file in a DNG wrapper, not a raw DNG file. As TIFF is RGB, meaning three colors per pixel (whereas raw is one color per pixel), it is completely as expected that the DNG file will be larger than the raw file.

As of Sept 13, 2026 edited photos in LRC still will randomly not open in PS although PS opens but there is no image file. Adobe we are paying you a monthly fee to fix this, Have reinstalled both and this fix doesn't help. Everything worked ok until latest update.

Latest version of LR and Photoshop Beta 27.11.

I can’t open files from LR to Photoshop. It gets stuck at around 75% on the progress but it doesn’t open. Rendering a RAW to DNG works. 

But, there is a bug with the DNG render… I shoot in 4:3 ratio on my Sony camera but the actual ratio of the raw file is 3:2. The problem is that if I reset the photo to its 3:2 ratio and then I choose render to DNG, it defaults to 4:3 so basically crops the image. The only work around I found is to trim the file slightly from 3:2 and then it will render ok.

The attached photos show the difference in ratios. Also the DNG is 40% bigger in size!!! That’s crazy!

Won’t open a dialog box? What do you mean with that? Do you mean this?

Right after OS Tahoe update, photos in LR classic won’t open in PS Beta, dialog box is missing

I am using LrC v. 15.5.1

Camera Raw 18.5.1

PS 27.10.0

iMac 24” M1 chip 2021

Canon CR3

Until today, I have been able to choose edit in Photoshop from the drop down menu when right clicking the photo I am working on.  Now when I choose that option, PS opens but the photo is not there.  

Things I have tried that did not help:

Restored preferences to their defaults

Uninstalled both LrC and PS and reinstalled both making sure to reinstall PS first

Opening the original unedited file from LrC

Things that did make a difference:

I can send a photo to Topaz and have it come back as a tiff file and it will open in PS

I can open the original file into camera raw from my computer and from the external HD

I'm having an issue with the Lightroom Classic → Photoshop 2026 workflow.

Normally, I right-click a photo in Lightroom Classic and select Edit In → Edit in Photoshop 2026, and Photoshop opens the photo with all of my Lightroom adjustments applied.

Recently, I've noticed that this stops working whenever I use Denoise in Lightroom Classic.

For example:

• Photo with normal Lightroom adjustments → Edit in Photoshop 2026 works normally
• Photo with no Lightroom adjustments → Edit in Photoshop 2026 works normally
• Photo with Lightroom adjustments + Denoise → the photo does not open properly in Photoshop

I've also tried Open as Smart Object in Photoshop, and that doesn't work either when Denoise has been applied.

Is this a known issue with Lightroom Classic and Photoshop 2026, specifically with AI Denoise? Is there a setting or fix that would allow me to continue using the normal Edit in Photoshop 2026 workflow while retaining the Denoise result? This only starting happening recently. 

My current system versions:

• Adobe Classic - 15.5.1
• Camera Raw - 18.5.1
• Photoshop 2026 - 27.10.0
• Mac Mini - Tahoe 26.6.2

Any help would be appreciated.

I have the same issue, Images do not open from raw in Bridge with Adobe Photoshop 27.10.0
