P: Color profile missing after merging Apple ProRaw images into a panorama

Apple ProRaw images taken in Apple's camera app on my iPhone 14 Pro generally work well in LrC these days, which is great. In LrC I often use the "Apple ProRaw" profile.

 

When I perform a panorama merge of these images, however, LrC reports that the resulting .dng file is using the profile "Apple Embedded Color Profile" but shows an exclamation mark: "Profile missing." See attached screenshots.

 

I wonder if this is an inadvertent result of LrC's rule that only Apple ProRaw files have the option of the LrC ProRaw profile, and that the merged file is not recognized by LrC as a ProRaw file. Can this please be improved, or is there a workaround?

 

Thanks,

Wallace

    Thanks, @johnrellis, but doing so had no effect:

     

    • For the merged .dng that I posted on OneDrive and whose profile I had already changed in LrC to "Adobe Standard," after exiftool the profile in LrC remained "Adobe Standard" and no new profile options were available.
    • When I performed the panorama merge again and left the new .dng's profile in LrC showing that "Apple Embedded Color Profile" was missing, after exiftool the profile in LrC was unchanged and "Profile missing" was still displayed.

     

    FWIW, when I used exiftool to read that merged .dng after I exported the metadata in LrC, "ProRaw" did appear in the tag "Look Name". Here were the nearby tags:

     

    Look Name : Apple ProRaw
Look Amount : 1
Look UUID : D866CAE82BD24C3F896B6762BDDA6C50
Look Supports Monochrome : false
Look Supports Output Referred : false
Look Group : Profiles
Look Parameters Version : 15.4
Look Parameters Process Version : 15.4
Look Parameters Profile Gain Table Map: 100
Look Parameters Convert To Grayscale: False
Look Parameters Camera Profile : Apple Embedded Color Profile

    I found the same tags and values in the source ProRaw image that I had fed into the panorama merge, so it looks like LrC is handling the source image and the merged result the same in this regard.

    Has anyone on the thread confirmed that Camera Raw fails similarly?

      Select two sample Proraws that cause this problem when merging. Upload them to Dropbox, Google Drive, or similar, and post the sharing link here. That will allow Adobe to reproduce the problem and get this filed as a formal bug report.

      Sure, here's a set of three ProRaw files and the resultant panorama merge exhibiting this problem:

      I see the same problem with those samples. Photo Merge is forgetting to copy the metadata field EXIF:ProfileName from the source .dngs to the merged .dng.

       

      You can work around the bug by using the free Exiftool utility:

       

      1. In LR, select the merged .dng and do Metadata > Save Metadata To File.

       

      2. In Terminal, execute this command line:

       

      exiftool -profilename="Apple Embedded Color Profile" <path of merged dng>

       

      3. In LR, do Metadata > Read Metadata From File.
