Dealing with Lightroom Lens Profiles

Lightroom Classic CC supports a wide range of lenses but if you're not shooting in RAW you'll probably be out of luck if you want to apply a lens profile. All the built-in lens profiles were made with RAW files in mind. If you're shooting Jpeg then you're out of luck.

I usually shoot RAW but a few weeks ago I used Jpeg to do some street photography. All was well until I tried to correct the lens distortion. Lightroom couldn't find any lens profile! I thought my Lightroom install had been corrupted somehow. The list of lenses only included one Tamron lens, and not the right one.

After much searching and testing I figured out what to do. Paths are for a Mac. You'll find Mac and Windows paths in this blog post by the Lightroom Queen but the ideas are the same. Copy file, rename, edit, restart Lightroom.

  • Custom lens profiles go in the directory ~/Library/Application Support/Adobe/CameraRaw/LensProfiles/1.0/
  • The built in lens profiles are packaged with Lightroom, so find Lightroom in Applications, right click on it and then "Show Package Contents" to browse into it. You'll find the lens profiles in Contents/Resources/LensProfiles/1.0/
  • Look for the profile for your lens and copy it into the same camera/lens/ directory structure in the ~/Library/Application Support/Adobe/CameraRaw/LensProfiles/1.0/ directory.
  • Rename the new lens profile file, removing the " – RAW" string from the end of the filename.
  • Edit that file in a text editor and change every instance of stCamera:CameraRawProfile="True" to stCamera:CameraRawProfile="False". There will be quite a few of them for a zoom lens.
  • Restart Lightroom, apply lens profile to your Jpeg file.
