Newbies / Re: Moving Metadata from Hidde...
Last post by StarGeek - Today at 12:29:56 AMWhat do you mean by "hidden Sony field"?
Use the command in FAQ #3 to get a list of all tags in the file and look for the name of the tag you want to copy. Then you would run a command like this, replacing "TAG" with the name of the tag you found
exiftool "-UserComment<TAG" /path/to/files/
This command creates backup files. Add -Overwrite_Original to suppress the creation of backup files. Add -r to recurse into subdirectories.

Last post by jaethomps - April 03, 2025, 11:18:16 PMCan you help me with the code for moving metadata info from the hidden Sony field to the usercomment so that I can make this change to an entire folder of images at once?
Thank you so much!

The "exiftool" Application / Re: Copying creation date from...
Last post by Phil Harvey - April 03, 2025, 09:30:46 PMThis is what I get on my MacOS 10.14 system:
So setfile doesn't seem to handle pre-1971 dates as wywh said.
- Phil
Code Select
% exiftool a.jpg -filecreatedate=1966:01:02\ 03:04:05
1 image files updated
% exiftool a.jpg -filecreatedate
File Creation Date/Time : 2102:02:08 09:32:21-05:00So setfile doesn't seem to handle pre-1971 dates as wywh said.

The "exiftool" Application / Re: Don't output tag name when...
Last post by StarGeek - April 03, 2025, 03:51:35 PMNo.
Here's a previous post on the subject, though only the first half applies here.
Piping through tail would be the easiest. If you're on Windows, MSys2 is a port of Linux commands to Windows. Very useful as Linux commands are very powerful and there are a lot of examples on the web for using them.
There's also this post which has a Window BAT solution using findstr.

The "exiftool" Application / Don't output tag name when out...
Last post by ericconn - April 03, 2025, 03:38:26 PMIs there a command to not include the tag names when writing to CSV? I recently realized that you can concatenate with >>, but would like to avoid having to always remove duplicate rows when doing this. Thanks so much.

The "exiftool" Application / Re: Copying creation date from...
Last post by StarGeek - April 03, 2025, 02:38:21 PMI'm assuming you mean -FileCreateDate because otherwise, the command would instantly fail as "FileCreate_Date" isn't a tag.
What version of exiftool are you using?
In the past, there were problems with file dates before 1970, but I thought that was a mainly Windows problem.
On Windows, copying a 1966 FileCreateDate will work correctly with recent versions of exiftool.
And just to verify, you have setfile installed? See the notes under FileCreateDate on the Extra Tags page.

The "exiftool" Application / Re: Copying creation date from...
Last post by wywh - April 03, 2025, 02:06:48 PMDo not bother with pre-1970 file dates. Instead, concentrate using internal metadata dates that might be supported down to year 1904-001 depending what app and file format you use.
Unix time begins at 1970 GMT/UTC so Unix timestamp 0 corresponds to Thursday, January 1, 1970 12:00:00 AM GMT.
Usually pre-1970 file dates dates are reverted to some weird date after a reboot.
FileCreateDate 1970:01:01 00:00:00 UTC is the earliest date macOS supports. Some apps might temporarily set it to an earlier date in Finder dates but usually after a reboot it might be changed to some weird future date.
On the other hand, the earliest FileModifyDate seems to be something like 1677:09:21 01:52:33+01:40 (YMMV, the exact time might depend on your location and timezone).

The "exiftool" Application / Copying creation date from one...
Last post by mboursnell - April 03, 2025, 12:08:44 PMHi,
I want to copy the file creation date from one image file onto another.
I am on a M1 iMac, in the Terminal. I am typing:
exiftool -tagsFromFile Test1.jpeg -FileCreate_Date Test1_new_date.jpeg
But the original date of 1966 is copied over as 2102.
What am I doing wrong?
Thanks,
Mike
