With a thousand newly scanned color transparencies, I want to save the scan company's unwieldy filename as data just in case I ever have to return to the archived original scanned file (OK, I'm paranoid, so what?). I can't figure out how to do this using the help files and don't know if it can even be done. I tried to use the tag "XMP Photoshop\author Title" as a re-purposed container but it can be put in any text field, I don't care.
I believe xmp:Title would be the appropriate place to stick it, though I could be wrong.
From IPTC Standards "IPTC Core" Schema for XMP pdf (http://www.iptc.org/std/Iptc4xmpCore/1.0/documentation/Iptc4xmpCore_1.0-doc-CpanelsUserGuide_13.pdf)
"Title
This field can be used as a shorthand reference for the image or "photograph" — primarily for identification. The title of an image may take several forms; for photographers this might be the filename of their original scan or digital camera file"
The basic command would be this, where you would replace "<DIR/File>" with the Directory or Filename you wish to use:
ExifTool "-Title<Filename" <DIR/File>
You could add -overwrite_original to avoid making backups once you were sure that it worked properly and -r to recurse down through all directories.
Hope that helps
Worked like a charm, thanks for the help
