I'm a photographer and I'm trying to learn how to create a different kind of preset. It's not a conventional preset created in Adobe Lightroom, it's different! It seems that this preset imports masks created in Photoshop into Lightroom, but this function of importing masks does not exist by default in Lightroom.
I acquired some presets that do this and when I opened the file with the text editor I verified it uses RDF. XML.
Plugins for Lightroom are made using Lua.
I would like to learn how to create the presets this way. I don't want someone to create the presets for me. I want to learn how to create or develop a plugin for Lightroom that allows importing masks to later create a preset with that mask.
