Writing to XMP Photoshop fields using ExifTool

[Sampoline]

Hi all,

I have images that need some fields to be written through ExifTool. These fields are Author, Author Title and Description Writer. I can't seem to figure out which tags relate to these in Exif. I've tried Artist, Creator, Producer, Title, etc. All seem to neither write to Author or Author Title. And there's no author tiff tag in exif.

Does anyone know which tags these relate to? Thanks.

I don't have Photoshop so I can't test to figure out.  But it's easy enough to do.  Fill in the entries there in photoshop in a test file and save.  Then run exiftool (the command in FAQ #3) on the test file and look for the data you entered in PS.  There's a chance the data will be entered EXIF and XMP, maybe IPTC as well.

From a quick investigation, these look like mainly IPTC tags, for which you can find documentation here http://www.iptc.org/std/Iptc4xmpCore/1.0/documentation/Iptc4xmpCore_1.0-doc-CpanelsUserGuide_13.pdf

Plus https://www.iptc.org/std/photometadata/documentation/userguide/#_rights_information

You will also find IPTC tags are now part of xmp and Phil has provided documentation https://exiftool.org/TagNames/XMP.html#iptcCore and https://exiftool.org/TagNames/XMP.html#iptcExt.

An example ExifToll command to set one of these tags would be -iptc:by-line=Fred filename.ext
