Metadata Alldates error

[nikoner]

Hello hope someone can help with this.

I am trying to change a batch of photos to have all the date related metadata to move ahead 1 month, my line is below. it is reading errors.

MacBook-Pro:~ aprier$ exiftool -AllDates+= "0:1:0" /Users/aprier/Users/aprier/Documents/Photos/

what should i do to make it work?
Errors below:

Error: File not found - 0:1:0
Warning: [minor] Oversized SubIFD1 StripByteCounts (24390144 bytes, but expected 21341376) - /Users/aprier/Documents/Photos/DSC_6972.NEF
....
    1 directories scanned
    0 image files updated
   29 image files unchanged
    1 files weren't updated due to errors

Thanks so much for your help.

Remove the space between Alldates+= and the amount you want to shift.
-AllDates+="0:1:0"

The error shows that exiftool thinks you're looking for a file called 0:1:0, which indicates that it is reading -AllDates+= "0:1:0" as two separate items instead of the single item it should be.

Also, your command will only shift the time by a minute.  When only one set of numbers is given, exiftool will apply the shift to the time portion of the timestamp.  To shift the date section, you need to add a space and a 0.  In other words, also "shift" the time by 0.  See Shift.pl docs for details.

So to shift ahead one month, you would use
-AllDates+="0:1:0 0"
or even just
-AllDates+="1:0 0"

Thank you it worked! thanks.

Is there a way to change the 'metadata date' labeled in Lightroom that way? it shows today instead of the date. all other dates changed fine.

Thanks

AllDates is is just a shortcut for DateTimeOriginal, CreateDate, and ModifyDate. To change the date of the metadata as well, use -MetadataDate+="0:1:0".

Cheers,

Hello
Still getting an error for this one. What is typed incorrectly? Using a mac.

Thanks so much,

Sorry, should have paid a bit more attention to your first post.

Your error is File not found.  That means that there is something wrong with your path to your photos.  I'm not familiar with the Mac but it looks like you're duplicating part of the path: /Users/aprier/Users/aprier/.

If you drag your "Photos" folder onto the terminal window, you should get the correct path to the Photos folder.

Solved, you guys rock! thank you

If you are not familiar with the command line, a useful hint is not to use

/Users/aprier/Documents/Photos/

but to use

~/Documents/Photos/
