(These instructions presume you’re using macOS)
I have several Lightroom user and export presets that I wanted to back up. Digging into Lightroom, I realized that these presets are stored as text files, which makes them good candidates to back up using version control.
I set mine up to be stored in a single git repo on BitBucket. If you haven’t done so already, create your git repo.
To find your presets in Lightroom, go to Develop. Right-click one of your presets, and choose “show in Finder.”
Move up two directories, open a terminal, and initialize your git repo here.
Stage, commit, and push your custom preset files, and you’re done!
