In gThumb 2, the IPTC date was treated as authoritative: if the comment file was missing or the date differed, the comment file date would be replaced with the IPTC one. This seems to have changed in gThumb 3. If the comment file is missing, the date is re-created from the EXIF date, rather than the IPTC date. Further, the default behaviour in the comment/metadata dialog is to replace the date with the EXIF date, even if an IPTC date and comment date are already set.the date is read from the following fields, in decreasing priority order: Exif::Photo::DateTimeOriginal Xmp::exif::DateTimeOriginal Exif::Photo::DateTimeDigitized Xmp::exif::DateTimeDigitized Xmp::xmp::CreateDate Xmp::photoshop::DateCreated I don't know why the IPTC date is not present, maybe it was just overlooked.This new behaviour is a problem for me. I keep my camera clock in UTC so that I don't need to worry about changing the camera clock when I travel. However, I want the display date on my photos to reflect the local time zone where they were taken, so I change the time in the comment. With the gThumb 3 behaviour, I need to manually correct the time every time I edit a photo's comment, rather than just editing it the first time and trusting gThumb to leave it as I left it. Is there any particular reason for the new behaviour? If not, any chance that it could be reverted to the old gThumb behaviour?gThumb 3 has two possible behaviours, that you can change in the preferences dialog: 1) keep the embedded metadata in sync with the XML metadata: in this case after reading the embedded metadata the XML metadata is updated if it differs; when writing the metadata both embedded and XML metadata are updated. 2) embedded metadata is not updated: in this case after reading the embedded metadata: *) if there isn't a XML comment file, the XML metadata is updated with the embedded metadata. *) if a XML comment file exists, the embedded metadata is ignored. - Paolo
Is there any way to make the date field in the comments dialog default to "Do not modify"? Rennie
