Question

LR 13.2 fails to import a TIFF that many other apps can open

LR 13.2 / Mac fails to import the attached "bad.tif" even though Photoshop, Mac Preview, Image Viewer, XnView MP, and Windows Photos open it without complaint:

 

The issue seems to be that EXIF:BitsPerSample = 16. Using Exiftool to change it to "16 16 16":

 

exiftool -exif:bitspersample="16 16 16" file

 

lets LR import the file. (The attached "good.tif" is "bad.tif" so modified.)

 

I don't know whether "bad.tif" or LR is non-compliant with the standard.

    I guess that explains the problem, what is my easiest solution Open in Luminar and then save as so I can import into Lightroom?

    Is there a plan to fix the problem?

    Thank you

    Light room classic Newest version 2024 Mac OS Ventura 

    Lightroom doesn't import files created in a Windows machine - Program is Registrax. Also, it doesn't see the thumbnail and reports the files as corrupted. Photoshop and other Mac applications (Luminar, and  Preview) open them fine. Opening in photoshop and saved as a copy is a workaround but clumsy. Tech support was unable to help. Seems like a bug in Lightroom. I think this worked in prior versions. I could drop the file but it is 40 Meg.

      Here is a sample file. Taken of the sun as a SER video, then created as a TIFF in autostakkert, then refined in Registrax. The files done in Autostakkert import fine, and this file is readable in Preview. Again Lightroom Classic on the Mac newest version does not import. Thank you for your help.

      I filed a bug report:

      I don't know the TIFF standard very well, so I can't say whether it's the TIFF file or LR that isn't strictly complying with the standard.

       

      Workarounds:

       

      1. Open and resave the file in Photoshop. You can resave a whole batch at once, though I forget the command sequence.

       

      2. Use the open-source Imagemagick "magick" utility:

       

      magick original.tif new.tif

       

      3. Use the free Exiftool utility:

       

      exiftool -exif:bitspersample="16 16 16" original.tif
