It's the same problem with kipi-plugins 1.4.0 ? Which Exiv2 version you use. I recommend last 0.20.0... Gilles Caulier (In reply to comment #1) > It's the same problem with kipi-plugins 1.4.0 ? I Don't know, I use Gnome and it's not easy to recompile. I usually wait until the packagers make it available. > Which Exiv2 version you use. I recommend last 0.20.0... exiv2 0.19 But I see it in Digikam's picture browser too (the time difference). Don't know if digikam uses exiv2's libraries though. Yes digiKam use Exiv2, through libkexiv2 interface designed for KDE... Gilles On 02-09-10 09:27, Gilles Caulier wrote:

This evening I'll check in Windows what the exif data says.

No need windows. Compare metadata with Exiv2 and Exiftool command line program, between your original ARW file and the DNG file created. Gilles Caulier > No need windows. Compare metadata with Exiv2 and Exiftool command line program,
gerbenr@gerrit:2010-Nederland$ exiftool DSC01646.ARW |grep Modify
Modify Date : 2010:08:25 15:36:37
gerbenr@gerrit:2010-Nederland$ exiftool DSC01646.dng |grep Modify
Modify Date : 2010:08:25 16:36:37
1 hour difference here, too.

SVN commit 1174969 by jmueller: Use timestamps from libkexiv as Libraw do not support daylight savings time. BUGS: 249785 M +22 -15 dngwriter.cpp WebSVN link: http://websvn.kde.org/?view=rev&revision=1174969 Jens, i'm not sure if it's relevant. in all case, take a look for info : http://dev.exiv2.org/issues/732 Gilles Interesting link, indeed. I looked at dcraw/libraw source and found that they do not support daylight savings time correctly with current implementation. But what I see from exiv2 everything seems to be fine for me - but I'll do additional checks. About kipi-interface: yes that could also be get from interface. Beside from timestamps the more interesting parts are xmp author, keywords and comments as they some raw formats do not support changes here, right? Jens, Sorry for my late reponse... I'm too busy everywhere (:=))) With 2.0.0, XMP sidecar support have been added to digiKam. kipi interface from digiKam core export to plugins the XMP sidecar settings used to manage these metadata files. Typically, XMP sidecar are used with read only files to store extra metadata. DNG converter must be able to deal with these files. Gilles Caulier |
