Lightroom Classic includes the ability to export the same photos as multiple sizes/formats in a single export, content aware fill for panorama edges and more. It does require a catalog format upgrade and there are updated system requirements, so you may want to wait a few days before upgrading.
    Lightroom (cloud-based service) has export options (such as TIFF format, renaming and color space), custom sort order on the desktop, copy/paste to multiple photos on iOS and more.
    The Missing FAQ and Edit Like a Pro eBooks are already updated for the changes.

Nikon Transfer 2: version 2.13.3

Hello all,

At the moment I cannot import some of the photos I made with my Nikon D7500. Lightroom will indicate “Preview unavailable for this file.”. If I do select the files and click ‘import’, Lightroom indicates: “The files cannot be opened by Lightroom”.
Below you will find some notes and things I tried:
  • Change EXIF information
    using exiftool I changed the camera type of the files to Nikon D90 (my previous camera). That didn’t work out. Or I didn’t do it correctly
  • File transfer – file explorer
    Photos I transferred using the file browser are no issue. I can import these into Lightroom.
  • File transfer – Nikon Transfer
    The files were transferred from my camera to my laptop using Nikon Transfer. I did confirm that the files were on my laptop and I could open\preview them using the file explorer, so I assumed everything was fine. Unfortunately, I deleted the photos on my camera after transferring.
  • Nikon Capture / Microsoft Photos
    I installed Nikon Capture, which was able to open the files, so as the build in program of Windows to view pictures. I don’t see what is wrong with the flies
  • Copied files
    I tried copying the files to a different location: no effect.
  • Updates
    I updated Lightroom and windows and rebooted my laptop several times
I will no longer transfer my photos using Nikon Transfer, but in the meantime I have quite some photos I cannot process. I will be very happy if anyone could help me with this issue!
Thank you in advance!

Nikon transfer is known to make files unreadable by Lightroom. I see that you'll not be using it in the future.

I seem to recall that there is a way to fix them, but my recaller isn't all that reliable--there might not be. You can probably use some Nikon software to convert them to TIFF and import those into Lightroom.
