Following the release of Lr Classic 13.3 I have a potential bug that i cannot understand.  If i import a Nikon NEF raw file Lightroom applies Process Version 6 to it.  If i send the same file through DXO PureRaw 4 and then import the resulting DNG file into Lr Classic it applies Process Version 5.

 

Not sure if this is a LrC or DXO issue but i cant remember it happening before the 13.3 update.

I am using Lightroom Classic Version 6.14.  I have been having a problem with the Basic Panel in the Develop Module.  When I import and then attempt to edit a Canon (.cr2) file within the basic panel, I see the following options for editing:  Exposure - Contrast - Highlights - Shadows - Whites - Blacks

Everything works normally.

 

However, if I first use DxO PureRaw 3 on the .cr2 files and then import those files (.dng) into LightRoom I see different options for editing:  Exposure - Recovery - Fill Light - Blacks - Brightness - Contrast

 

Why are the basic panels different?  Any help or suggestiions would be appreciated.

Those .dng files are being edited using an old Process Version. In the develop module, under the histogram, click on the lightning bolt icon to change to the current Process Version.

    Select a sample file processed by DXO and upload it to Dropbox, Google Drive, or similar and post the sharing link here. We can put it under the microscope and confirm it's DXO specifying process version 5.

     

    Note that as soon as you start editing a PV 5 photo, LR will automatically convert it to PV 6. The differences between PV 5 and PV 6 are minor:

    Manny thanks for looking into this.  

    Here's a DXO PureRaw generated dng file: https://1drv.ms/i/c/3585b20cc59ee0f5/EcCWYvJdp_BDu27GI3xKYxYBSofVfTTitmQCpF-JK0hAdw?e=w1agCz

    This one and a number of others are now openning with Process Version 1 showing the original Exposure, Recovery, Fill Light and Blacks sliders rather than the later Highlights, Shadows, Whites and Blacks.  The following link shows a screenshot of Lightroom Classic after importing the file

    "my raw defaults (preferences>presets>global) are set to Camera Settings. ... I switched back from Camera Settings to Adobe Defaults and that has cured the Process Version error (now importing as PV6)"

     

    I see the same behavior when setting Preferences > Presets > Raw Defaults > Global to Camera Settings. Note that after importing, when you click Reset, Process Version changes to 6, Profile changes to Camera Standard, and various Detail settings get non-zero values. I think you're going to have to sort out the behavior with DXO.

     

    DETAILS

     

    The DNG includes Develop settings, both defining camera defaults for that file and current Develop settings. I've attached the XMP metadata to this post.  Camera defaults are lines beginning with "crd:" and current develop settings are lines beginnig with "crs:".

     

    When LR imports the file with Global set to Camera Settings, it applies the camera defaults defined in the DNG and then applies the develop settings. It's this combination of defaults and settings that is setting Process Version to 1, Profile to Adobe Standard, and Detail settings to 0.

     

    After importing, when you click the Reset button, LR resets the develop settings to the camera defaults specified in the file. At this point, Process Version goes to 6 and Profile to Camera Standard,.

     

    Also strange is that the file's camera defaults define various Detail settings:

     

     

    But the develop settings define all those to be 0. So when you first import the file they're all 0, but when you hit Reset to apply the camera defaults defined in the file, they go to the settings above.

     

    I'm not sure what DXO is trying to accomplish here, and whether this is a LR bug or DXO bug. But DXO knows what they want, so you'll need to sort this out with them.


    I have some more information regarding this issue after speaking to DXO and looking into some of their suggested tests.

    Opening the raw NEF file in Photoshop and viewing the XMP information in the File Info menu option and selecting Raw Data there is a line entry that says:
     
             <crs:ProcessVersion>15.4</crs:ProcessVersion>
     
    Opening the file after passing through DXO PureRaw 4.2.0 the line has changed to:
     
             <crs:ProcessVersion>5.0</crs:ProcessVersion>
     
    I tried turning off all adjustments in PureRaw but got the same entry.
    For comparison I tried the noise reduction and optical correction using DXO PhotoLab 7.7.0 and the processed dng imported into Lightroom Classic correctly using Process Version 6.  Viewing the  XMP data again in Photoshop the line entry stated:
     
             <crs:ProcessVersion>15.4</crs:ProcessVersion>

    i.e. the same as the original raw NEF file.

    So it seems that DXO PureRaw is changing the     value for the <crs:ProcessVersion> line entry from 15.4 to 5.0 while PhotoLab 7 doesn’t do this.  This seems to instruct Lightroom to apply the earlier process version. As this entry is only read when Lightroom Classic is set to use Camera Settings on import it explains why it doesn’t cause the same problem when importing with Adobe Defaults.
