Title: Lightroom 3 does not see EXIF time change
Post by: MarcelH on March 05, 2012, 06:01:58 PM
when i shoot with two cameras the times are not the same. one camera is 12 minutes 9 seconds off, so i did the command:

exiftool "-AllDates+=0:12:9" filename

when i check the file i see that the 3 dates they are changed:
Code Select

Create Date                     : 2012:02:10 09:55:29.00
Date/Time Original              : 2012:02:10 09:55:29.00
Modify Date                     : 2012:02:10 09:55:29.00


however, Lightroom 3 does not "see" the change, even when i sync the directory. how can i let Lightroom recognize the change in EXIF ?

Try this to see what other date/time information exists:

exiftool -a -s -time:all FILE

If the problem isn't LR's database (which I'm guessing it isn't because you said you sync'd the directory), then the only other possibility is some other metadata that LR is using.

To get Lightroom to read the updated timestamps in the files, select the files in question in the Library module of Lightroom.  Then right click and from the menu that appears choose Metadata -> Read Metadata From File option.  Lightroom will then read the metadat from the files and update its database.

I have the same problem with NEF files being updated with exifTool and not recognized by LR3 or LR4.  I've done the metadata - read from file in LR and LR still doesn't show the new date/time.  I've done this to JPG files in the past with JHEAD and it's not a problem.  The difference here is I'm using exifTool on NEF files.  LR creates sidecar XMP files for the NEF files.  I think LR is displaying date/time from the XMP sidecar file.  I'm going to try deleting the sidecar file and then doing the metadata - read from file again after updating the date/time in the NEF using exifTool and see if that solves my problem.

If there is an XMP sidecar file, you could use ExifTool to update it too...

Shouldn't good programming have updated the database by automatically recognizing that the photo had changed?  This stuff is so offputting.

Sorry, such moans are off topic for this forum.  Indulge me.

Hi Alan,

Very true.

Thanks Phil, including the .xmp files in the -AllDates run got everything updated.  LR displays the correct date/time after running exiftool -AllDates-=1 d:\dsc_* and LR metadata - read from file.  The good news is DST is about to start so no sense in "fixing" my camera clock.  I'll be good at least through the summer and most of the fall.
