I changed the keywords on a file via photomechanic's Structured Keywords Panel. I UNCHECKED the append box, as I wanted to make sure that I completely replaced the keywords.
My PM preferences for jpeg, tiff, psd, dng (it was a jpg file) indicate to "Update both embedded IPTC and IPTC4XMP". There is no XMP file in the directory.
I noticed that my Apple Finder smart folder refused to update it's results. I did a Get Info in the finder, and still saw the OLD keywords. Then I looked a the file in Nikon Capture NX2 and also saw the OLD keywords.
The capture NX manual uses the term XMP/IPTC info, but doesn't say much else about what standard it adheres to.
Is there an explanation for this?
