I would like to find images which are missing a certain keyword tag, so I can add that tag as needed.
In a smart collection, you can set the criteria to show something like
Keywords does not contain Gorilla
which will find any photo that doesn't contain the keyword gorilla. You may want additional conditions to narrow things down further.
Thank you. That is want I want to do, but I do not see how to add that parameter to Smart Collections. Can you please advise how to do that?
Create a new smart collection. Once you start the process of creating a new smart collection you are given options on what to include or exclude from the collection
I would like to find photos without ANY keywords
"I would like to find photos without ANY keywords"
Make a Smart Collection as the screenshot below
Or use the Library Filter bar (View > Show Filter Bar) if you want to restrict the search results to the currently selected folder(s) or collection(s):
Thanks for the alternative suggestion!
