When I add/change an Exif Value in a .jpeg that had previously been opened by photoshop, the new value is not visible in Photoshop. I guess that is because Photoshop keeps the data redundant in its XMP metadata. What would be the correct way to update the data in both locations?

Hello Erwin,

If file has XMP metadata in this case Photoshop use it not EXIF information.
So if make some correction in EXIF you should do the same in XMP:
Code:

Aurigma.GraphicsMill.Codecs.ExifDictionary exif = new Aurigma.GraphicsMill.Codecs.ExifDictionary();
            exif[Aurigma.GraphicsMill.Codecs.ExifDictionary.Artist] = "John Doe";
            jpegWriter.Exif = exif;

            Aurigma.GraphicsMill.Codecs.XmpData xmp = new Aurigma.GraphicsMill.Codecs.XmpData();
            Aurigma.GraphicsMill.Codecs.XmpValueNode node = new Aurigma.GraphicsMill.Codecs.XmpValueNode(Aurigma.GraphicsMill.Codecs.XmpNodeType.SimpleProperty, "John Doe",
            Aurigma.GraphicsMill.Codecs.XmpTagNames.DCCreator);
            xmp.AddNode(node);
