Date was set wrong in my camera, so file creation dates are all in 2013. When I run
exiftool "DateTimeOriginal+=2:0:0" *.NEF
the change date, and not the creation date, is being set to the right date in 2015. But when I look at the NEF files on my Mac, it shows them to have been created or changed today.
How can I set just change the creation date year, and not affect the changed date at all? Can I do it with exiftool? Or do I need other software?
Read FAQ 24 (https://exiftool.org/faq.html#Q24) for some help understanding the date/time tags.
There is a round-about way of setting the FileCreateDate on a Mac. For details, see the notes for the FileCreateDate tag in the Extra tags documentation (https://exiftool.org/TagNames/Extra.html).
