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

This issue has arisen again with the latest Photoshop update, can anyone suggest what can be done now

Photoshop 27.10 has several serious known bugs. One of them:

They are known and the developer team is working to fix these. In the meantime go back to versoin 27.9.1

There is an alternative tactic when the normal “Open in Photoshop” external editing workflow does not work from Lightroom Classic. This is to create, within LrC, a named external editing preset which refers to the Photoshop executable (with choices associated for bit depth, file format and colourspace that are independent of the main settings for PS external editing).

When the usual Open in PS workflow happens, the creation of an image file on disk is deferred - until you later save one (or don’t). Conversion of Raw (if needed) and application of edits done in LrC are subcontracted out to Adobe Camera Raw to do; then the results from that are passed to Photoshop in memory as an unsaved image. This reports as document title the file name from the original source file: “NEF” or whatever. A TIFF or PSD is not made until when (if) you Save. It sounds as if something in that has not caught up with newer LrC functionality. Perhaps an ACR / PS version update is now needed.

When instead you use Edit in / [your named preset] from LrC, it is Lightroom Classic which executes the Raw conversion as needed, applies edits, and saves out an image file to disk. LrC is certain to be able to do this correctly all on its own, and no external dependence on ACR is involved. 

After LrC has saved this file, it imports it straight away. The external editor (maybe Photoshop, could be anything else) is then told to open the new file as a separate operation. So what you then see is an already-saved file. This you can further update, and then save changes to - or not.

Known issue. Please check for that before you post a new thread:

Just started happening today after update.  I have uninstalled both applications and reinstalled with no change.

When I edit my photos in Lighroom and I want to pull them into Photoshop, I will *right click, choose ‘edit in’ and then ‘edit in photoshop’. I choose ‘edit a copy with lighroom adjustments’. In the past I have had no issues with pulling in dozens of photos at once to edit. However, after the newest ps update a week ago, if I pull more than one photo into ps as described above it will crash the app. It will also pop up the raw editing window which used to not happen. I have changed nothing with my workflow or settings, the only change is the new ps update. Any bug fix in sight or work around? This unfortunately is slowing my workflow way down.

Hello Adobe,

I lost quite some time with this issue of denoise and Photoshop.

Why can you guys test things better before releasing?

I am relying quite too much on Lightroom Classic and Photoshop for my workflow.

Kind regards 

Tried without denoise and it workde, thanks for the tip

It’s not specific for open as layers. A single denoised file also doesn’t open.
