All of my scanned photographs have "Source Type" in IPTC Extension set to either of the following:
- Digitised from a negative on film
- Digitised from a positive on film
- Digitised from a print on non-transparent medium
I created a Smart Collection named "Shot on Film":
Match all of the following rules: Any Searchable Metadata -> contains -> Digitised
How come it shows 0 images? Is Lightroom not able to search in IPTC Extension metadata?
Lightroom can only search certain fields, so unless it's too much work, you could try using a different field for that info (I use "Description").
There are also some plugins that might be helpful -
Thank you Per for your answer. I tried the 'Extended Search' plugin and although it did not let me search by Source Type, it referenced another helpful plugin - Jeffrey’s “Data Explorer” which supports Source Type. So I could isolate collections by Source Type, and have applied appropriate descriptions within seconds. Now I can make my smart collections. Thanks!
