While the full version includes both XMP files & DNG files, this sample preset is delivered in DNG so that you can easily test it across LR Mobile, LR CC or LR CC Classic.
To use, simply import the DNG into your version of Lightroom. Select the photo inside your library, then create a new preset. Voila! You can test the new preset on all your awesome photos.
Alternatively, you can simply copy & paste the settings instead of saving it as a preset.
Enjoy!
