My girlfriend is a horse show photographer. She has a list of all the shows participants and is stringent about the way each collection is named. To save her time, she asks that I create the empty collections for her, so that she can later sort the photos into the correct collection. Rather than needing to type or copy paste these names of people, can I use a script or CSV file to import them to lightroom?
as far as I know this is not possible. Perhapst someone can write such an script for you.
But for me this sounds more like using keywords. And you can use keywords in the filter tab.
And you can import additional keywords as a text file.
To figure out its format, export a keyword list - the format is pretty obvious.
