Thanks! > I'm not sure what you mean by "...attach... to this ticket", so I've attached it to this e-mail, and I've also attached the output of "exiftool -a IMG001.jpg", which applies different names to the properties, just to make life easy for us. I think the date of the scan itself is given by: Exif.Image.DateTime Ascii 20 2002.04.07 09.47.26 and Modify Date : 2002.04.07 09.47.26 respectively by exiv2 and exiftool, while the OS's timestamp as reported by exiftool is: File Modification Date/Time : 2002:04:07 09:50:18+01:00 Michael PS I see that exiftool says that the Primary Platform is "Apple Computer Inc.", which is odd, because I have never owned an Apple computer, and the original scan was definitely made on a PC. ** Attachment added: "exiftool.txt" https://bugs.launchpad.net/bugs/644125/+attachment/1619761/+files/exiftool.txt ** Attachment added: "exiv2.txt" https://bugs.launchpad.net/bugs/644125/+attachment/1619762/+files/exiv2.txt -- Date information not imported with jpg files of scanned negatives https://bugs.launchpad.net/bugs/644125 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
