I started recently supplying Location metadata to my images (not geolocation, I do that in a few cases but hardly for all of them) and I thought »Hey, a smart collection that contains all images without location would be handy«. I then created one with
Location | is |
(the text box at the end is empty – not even whitespace) for lack of something like »is empty«. But now the collection shows no images at all, although I know there are still images with no location information there.
Is there a trick I just don't know or is it impossible to create such a smart collection? I noticed that the built-in smart collection that filters photos without keywords uses an »is empty« filter which exists for keywords but not for Location.
