Lightroom preset that is like Instamatic for IPhone

[rmargolis]

I have never used a LR Preset or Plug-in so in this area, I am a newbie. Is there a place to find a wide variety of Presets to import that are for creative purposes? I haven't been able to find what I am looking for. My goal is to find a Preset that will simulate wet plate collodion and possibly other effects of alterative processes. If I can't I know I can make my own however it will take time. When doing this sort of thing, I'm not particularly fast. 

Are the terms Plugin and Preset interchangeable? 

Thanks in advance, Roberta

Just Google "Lightroom Classic wet plate collodion preset". I found several. Plug-in is bit the same as preset.

Lightroom-Classic  comes with many default Presets installed.

I am sure you could find a starting point with one of these.

eg. The 'Creative' Group;

And Lightroom has a 'Discover' link where Adobe suggest you can get access to 50,000 presets -free!

No need to go to Google or buy.
