Question

Reference view displaying low res image

  • February 14, 2022

I run LR Classic 11.2 and Camera Raw 14.2 on Windows 10.

I shoot RAW, format is Olympus ORF.

 

Issue: When using the Refence View, quite often a low resolution/low quality preview image is displayed instead of a high resolution. This is annoying as I have to wait a few seconds until LR has decided what to display the Reference View. This is annoying and becomes time consuming.

 

Remedy: I have to "Set as reference" repeatedly until the image in the Reference View is displayed with the expected high resolution. Usually it cures the rendering at the first attempt, sometimes not...

 

Refer to attached screenshot of LR window with a side by side comparison of Reference and Active windows of the same photo at 100% scaling.

    Im also having this issue, see below. It does not seem to resolve even after waiting several minutes.

    Win 11/RTX 3060ti/546.01 NVIDIA Driver/Lightroom Classic 13.0.1

    Left side is pixelated, right side is down to pixel level

    I'm having a similar problem. Working on a shoot with some very deep blacks and the reference photo is rendering shadows with some funky colors and weird flattening. See attached screenshot. I'm using LR Classic 12.1 on Mac OS Monterey (12.6).

    In my case, the issue is still there regardless of the photo displayed as a reference. Adobe LR Classic is now on version 12.1 and Camera RAW is version 15.1. And my GPU drivers are updated.

     

    It's rather annoying as it makes the workflow so much slower... I haven't heard anything on this subject since the last reply one year ago.

      When you are working in the Develop Module Lightroom is not displaying from the prebuilt previews it re-renders the RAW file data and creates the display of the before and after.

      Increase your Camera Raw Cache, this is what is used when rendering in Develop Module.

      Hi Denis,

       

      Thanks for the suggestion. I have increased the Camera RAW cache to 10 GB (it was 5 GB before), checked the option to Use Smart Previews instead of Originals for image editing (it was unchecked) and also unchecked the option to Generate Previews in parallel (it was checked). I also have made sure the catalog is optimized. I do that quite often, take backups on weekly basis or even more often.

       

      Did this help? Well, not exactly. Let me try to describe it. 

       

      When reviewing photos at 100% scale:

      • When I left-click a thumbnail
        - in that vast majority of cases the photo is rendered in the Active window with the expected level of fine detail. It takes a second or so, which is OK.
        - In rare occasions, the photo is rendered in lower resolution. To remedy that I have to move the photo or zoom it out and in then the photo will be rendered in high resolution. 
      • When I drag a thumbnail to the Reference window, or right-click and Set as Reference then the Reference window either:
        - displays a high res photo after a second or so, same behavior as Active window
        - displays a low resolution photo and stays there
        - (less often) displays a low resolution photo and then after a while, maybe 10 seconds or so, displays a high res photo without me doing anything more to trigger that.

      To force a rendering in high res I have to move/zoom in/out the photo in the Reference window. I can also try to Set as Reference again. Sometimes I had to repeat this to force the high res rendering.

       

      The comment regarding the drive performance is not relevant. It's an internal drive and the computer is a fairly recent desktop, all other functionality in LR performs to my satisfaction wrt performance. Same for other apps.

      Has this always been the case (when using Refence View) or did you just notice this after updating LrC? If it is a new problem specific to this version and it is annoying and interrupting your workflow you could uninstall and roll back to the previous version. Not an elegant solution but it will solve the problem so you can continue your work.

      I just tested this and can't replicate the issue. When I place an image in the Reference frame there is a slight delay that lasts a couple of seconds but then both views are clear and sharp.

       

      Is it only this image? It shouldn't matter but what are you using for preview, Standard, 1:1?

      Hi,

       

      I can replicate the issue.

      Hi,

       

      I experience a slight delay too, perhaps a second or so until the photo is rendered with all the details down to pixel level, which is OK and also considering it takes some calculations for the app to interpret the contents of the file and render it. 

       

      It may on any photo that I open in the reference view, however not all the time. Likelihood is maybe one time out of three. I always use the Reference view in 100% in order to select the sharpest photos in side-by-side comparison.

      Hi,

       

      Do you have any progress to report on this issue?

      I've tried this on a few images and can reproduce it occasionally, and suspect it is because the image has not got recent standard and 1:1 previews available, or they might be on a slower disk drive. I suggest discarding the 1:1 previews of a range of images and recreating them. And maybe create new standard previews too. Note that if you make adjustments to an image its previews are no longer up-to-date and if speed is important then recreate them.
