LRC 12.0 Crushing Shadow Detail in Develop Module

  • October 19, 2022

I noticed after the update that files worked in Photoshop and saved back to LR display different amounts of shadow detail between the Library and Develop modules. The Library module is the correct one. When in the Develop module, all sliders are in their default state. When viewing in PS, all is good. When viewing in LR Library module, all is good. When viewing in LR Develop module, shadows are crushed. When exported to jpg, etc, shadows are crushed.

    Thank you for your prompt follow-up, Simon. I've uploaded three files. The original RAW as requested and two screenshots. One with the settings and graphics acceleration on and one with the setting and graphics acceleration off. The files are named accordingly. I'm currently running macOS Monterey 12.6.3 on a 2019 Retina 27" iMac 3.6 GHz 8-Core Intel i9 and Lightroom 12.1. Please let me know if you need anything else.

    Just discovered this post (sorry apparently way behind on reacting to updated threads). I downloaded your image and your screenshots and indeed heavy posterization in your GPU on screenshot. I downloaded the nef and tried it on my Classic install (LR 12.2 on Mac Book Pro M1 Max running ventura 13.2.1) and it does not do the posterization with GPU on and I can very nicely see the stand leg in the lower left with the raw settings as in the screenshot, so it either is something in Monterey that was fixed in Ventura or something specific to the GPU in your iMac.

    I've posted about this same issue with the release of LR 12. This is a problem with no solution other than turning it off, which works. This is still a problem with the new release, and now, in ARC, you're unable to switch it off. I use ARC via the Filter menu in PS for certain effects. Now, if I'm adjusting an image with heavy shadows, it's crushed and almost impossible to work with. This is SO FRUSTRATING. It's been a year now and still no solution other than replacing my computer, it seems. The interesting thing was this wasn't an issue with LR 11.5 or earlier, only after LR 12.

      I'm having similar problems. The shadows on the JPEG file (left) vs the shadows on RAW file (right). FYI: I unchecked the box in the menu and it didn't solve anything. Capture One works just fine. What gives Adobe!

      Please help!

      I'm starting a new post as my previous one, which started in Oct of 22 is locked. I have a 27" 5k iMac i9 with an AMD Radeon Pro Vega 48 graphics processor. When LR 12 was released last October, I experienced posterization in the deep shadows while working in the Develop module. When viewing the images in the Library module, the issue was not present. If I disable the "Use Graphic Processor" feature, the posterization problem goes away. It was mentioned in my previous post that it was most likely an issue with the graphic processor needing an update. Well, it's been 10 months now, and we've seen several updates to Apple's OS (currently running Ventura 13.5.1 and LR 12.5) as well as LR 12, and still no solution to this issue. I have a case opened with Apple's support team, and there's not much I can do about the AMD graphics processor since the updates for those appear in the Apple OS updates only. I do have a post in the AMD support community now, but I have yet to get a response. I did get a response from @simonsaith in my original post, which seemed hopeful, but again, nothing has come of it so far. The last I heard from Simon was in March of 2023. The original post is here: https://community.adobe.com/t5/lightroom-classic-discussions/lrc-12-0-crushing-shadow-detail-in-develop-module/td-p/13280383

       

      Please, somebody have a solution for this. From what I understand via Notifications I get in Photoshop, the use of the graphics processor will be forced in the near future.

      Please forgive me if I've misunderstood the process for getting this bug report in front of the right people. I posted about this after updating to LR 12.0 last week. There was little response to my post. Could I be the only one experiencing this issue?

      The issue is crushed shadows and posterization in the blacks in the Develop Module. All is good when viewed in the Library Module. One thing confirmed is that the issue goes away when Graphics Acceleration is disabled.

      Thanks Devin. This looks possibly a GPU render issue. Could you share a link to the raw image file with the settings that could demonstrate the issue so that our engineers can try to reproduce?

      Does it still do the posterization of the shadows when zoomed in? I have seen this before on the forum and it turned out to be a problem with color management and bit depth precision in the display profile when working with the 16-bit linear prophotoRGB color space Lightroom develop works in when translating to the display profile. How are you calibrating your display? Are you making sure to create a ICC v2 display profile as you should?

      Does the problem disappear when you test with GPU acceleration disabled in Lightroom's preferences?

      Yes. The posterization still exists when zoomed in.

       

      I use the Xrite system with their i1 Display device and save the profile. I use the profile created, but I'm unsure exactly if it's an ICC v2 profile. 

       

      Yes. The problem goes away when disabling the GPU acceleration. 

       

      Interestingly, this is not a problem on my earlier versions of LR, including 11.5.

      If the problem goes away when turning off GPU acceleration it is likely not a display profile problem. I would recalibrate the display if I were you as it might help. There is a setting in the i1 Display preferences for whether the software creates a v2 or v4 profile if I rremember correctly so worth it to ttry. The fact that the behavior changed when going to v12 might mean there is a bug in V12 with the GPU code and how it color manages. This is a bit of a recurring issue with Lightroom

        Please, Moderator: Do not move this to my Discussion post. It needs to be in the Bug section for Adobe to see it.

         

        I've reported this issue on a post located in the Discussion boards. I failed to select "Bug" for Conversation Type, therefore have seen minimal response and no solution. I understand I'm not supposed to post more than once about the same subject, but I don't know how else to get this info to the Bug section so that Adobe engineers will see it. 

         

        The problem is shadow detail is lost and crushed when viewed in the Develop Module. If I disable the GPU acceleration, the problem goes away.

        I went ahead and uninstalled and then reinstalled version 11.5 and the problem doesn't exist.
