I've also checked that the permissions to modify EXIF data (Preferences>Metadata2) in the main installation are on the default values indicated in the Help page. txt files of the EXIF output from attempting to use the modify tool in relative mode on a single file for the main database (ModifyRelMain.txt) and from the virtual database (ModRelTest.txt). I returned to my main database, performed a cold boot and a repair of the iMatch ver 2019.5.2 installation and found again that the modify tool worked properly in absolute mode but not in relative mode. I then updated to the latest version of iMatch and repeated the test with the same result, ie, flawless operation. I found I could modify the time and date in both absolute and relative modes using the tool. I made a database using copies of a subset of the troublesome jpegs.
I mainly use it in absolute mode, correctly setting dates on old scanned images.Īs a test, I set up Win10 Home in a virtual machine and loaded iMatch ver 2019.2.2.
Overall, I find the Modify tool extremely valuable. I'm almost certain this problem is recent, as I fixed another batch of his photos last week and also earlier fixed one of my own problems, when I photographed furiously in Amsterdam for two days before I remembered that my camera still thought it was on the other side of the planet.Īs I have updated iMatch in the last couple of days, I will try to see if that is the problem by installing the previous version on another computer and setting up a small test database. Taking the images one at a time and changing them using the Modify tool in absolute mode works well, but tediously, as does changing the data manually in the Metadata panel. As they are shot over the duration of an expedition, each has a different, but incorrect, time stamp in all time-related metadata fields (examined using the metadata panel).Īttempting to fix the problem by using the Modify tool in relative mode, for either single images or a batch, gives EXIF output (viewed in Output panel) that indicates changes have been made, but no metadata fields were actually changed. His are jpegs and all are out by 25 minutes. Like tomdriver, I am trying to align, in time line view, a stream of my photos with those of a friend. The more details you provide, the better we can help.I, too, have found problems recently with the "Modify EXIF date and time tool".
We don't see what you see and "Did not work" is not a good problem description. Like,ī) This is the metadata my file contains (from ExifTool Command Processor)Ĭ) This is what I have done in feature X ("Using the EXIF Modify Date and Time I changed the time from A to B)ĭ) This is what happened when I did that ("Error Message", "Time changed to C instead o B") It always helps to provide a minimum of details when you report an issue. Unless your local time zone is different from UTC by more than one hour. Changing the EXIF date and time by one hour (to match it to your local time zone) in the Modify Tool or stripping the time-zone offset in the Metadata Panel should do it. or simply trying to edit the various EXIF offset time fields) seems to work even on one photo. If the time-zone is wrong, change the time-zone in the MD panel to whatever matches your local time-zone offset. If IMatch/ExifTool map from EXIF->XMP, the local time zone is assumed (unless you have configured a different time zone). If the time zone is different from your local time zone, IMatch has to display an time-zone offset of course. IMatch displays XMP date and time, and these timestamps always include a time zone. Some metadata tags have time zone information (legacy IPTC, XMP) some don't (EXIF).
