Hello! There’s a short tutorial!
I use the latest version of Lightroom (Feb 2020 – Lightroom Classic). Make sure your program is up to date. If your Lightroom doesn’t accept XMP files, you can import the DNG files and save the presets one by one.
Click on plus button> import
Find the files on your computer. Select all and click on the import button
That’s it! All your filters are in your Lightroom folder. 😀
