Sorry for not getting back to you sooner! As for KPA not getting the refreshed exif description: did you calll "Maintenance" -> "Read EXIF info from files..."? Note that according to the Metadata Working Group Guidelines, "Description" should be mapped to the following fields: Exif: ImageDescription IPTC: Caption XMP: dc:description Just as a note: KPA currently uses only Exif.Image.ImageDescription. The description is read in DB::FileInfo::parseEXIV2() and written in Exif::Info::writeInfoToFile(). Ok. I finally got some time to look into this with more detail: > I edited the Caption field in Microsoft (Vista) Photo Gallery of an image. Ok. > I then opened the same image in KPhotoAlbum and that caption came in on the Description box in the Annotate Image dialog. At this point, the image was imported to KPA, and you apparently had "Use EXIF description" checked in the „Configure KPhotoAlbum...“|„General“ settings page. > I then edit the Description to something different and opened the image in Eye of Gnome and that Description still has the original caption as saved from Photo Gallery. The new description is not there. KPA has the policy of "don't alter the image files in any way". That means that meta-data is never written back to an image. This is a conscious design-decision on part of KPA. > If I reopen the image in KPhotoAlbum then the new description is still there. Yes, since it was written to the database of KPA. > If I go to the Edit EXIF dialog box, then the Title shows the same name as the caption was in Photo Gallery. KPA doesn't have a dialog box to edit the exif information. I'm assuming you mean the „Edit all metadata“ KIPI plugin. I just checked, and the plugin seems to ignore metadata coming from a host application such as KPA. > If I close that box, then the Description field in the Annotate Image dialog disappears. I suspect that is because the Caption box was blank (even though the box wasn't checked, BUG). Thanks for reporting that. I can confirm this is happening and that this is a bug. > If I go back and Edit Exif metadata again and this time change the Caption area, then that is copied into the Description of the Annotate Image dialog and it also shows up as the description in Eye of Gnome. It does not, however, show up as the caption in Photo Gallery. This is probably both an issue in „Edit all metadata“ plugin[1] and in Photo Gallery[2]: [1] When writing the exif ImageDescription field, the fields IPTC Caption and XMP dc:description should be synced (or at least cleared). [2] When reading the meta data, Photo Gallery should prefer the exif information over IPTC and XMP data. [1]+[2]: According to section 4.2.3 of the "Guidelines for handling metadata" by the Metadata Working Group (http://www.metadataworkinggroup.org/specs/) Assigning to KIPI-Plugins since the report as a whole is a better fit for the „Edit all metadata“ KIPI plugin. The kipi has already a "Sync JFIF Comment section" to synchronize this JPEG field with Exif, or Iptc or Xmp captions. Gilles Caulier |
