So you should.
And so nicely keyworded that I would also have found this image if I was
looking for (among other things) "chess", "corridors", or.... "lunatics".
No comment.
More usefully - also on Mac, you can use the command line tool "mdls" to apply
to an image (or any other file) to output all the fields extracted by the
'spotlight' indexer, so you can see just how it's mapped the various IPTC
fields. (On the NPG, we repeat values using multiple terms from different
vocabularies to maximise coverage, so it's harder to see exactly where it
picked up what; but it includes at least one of
