I've got a date problem on several images. The camera was off-timed, and I want to correct the files. I've used exiftool -allDate with some results, but not all the dates are corrected.
Those are the results of the commands I tried:
pipo@lapin:~/Images/temp/20140305 Salon de l'Auto$ exiftool -G1 -a -s -D DSC02037.ARW | grep Modify
[System] - FileModifyDate : 2014:03:05 20:40:30+01:00
[IFD0] 306 ModifyDate : 2014:03:05 08:07:57
[IFD1] 306 ModifyDate : 2014:03:05 09:19:57
pipo@lapin:~/Images/temp/20140305 Salon de l'Auto$ exiftool -a "-IDF1:ModifyDate-=1:12" DSC02037.ARW
Warning: Tag 'IDF1:ModifyDate' does not exist
Nothing to do.
Is there something I'm not doing right ?
It's just a simple typo: You meant "IFD1", not "IDF1".

Ok, I'm officially ashamed...
