How about -ImageDataHash? Can be set to one of 'MD5', 'SHA256' or 'SHA512' Not quite the same thing but close.

Developers / MacOS Finder Exiftool extensio...

Last post by greybeard - April 01, 2025, 06:32:37 AM

Would there be any interest in an extension that runs Exiftool directly from the MacOS Finder?

See attached screenshot of the Finder in gallery view which shows a preview of an image. When the ExifAction icon at the bottom of the Finder display is clicked Exiftool runs and displays the results in a separate window.

The basic principles are:
- runs from any Finder view (list, column, gallery or icons)
- select one or more image files and click the ExifAction icon within Finder to run Exiftool and display the results
- default or custom Exiftool commands (for example with/without unknowns, sort/no sort tags, short or descriptive tag names etc etc)
- does not require that Exiftool be installed on the computer
- allows user to keep control of when a new version of Exiftool is used
- access to the Exiftool output as a text file
- in its basic form does not require any knowledge of Exiftool syntax or the use of the MacOS terminal
- sandboxed and notarized by Apple to avoid any special installation techniques

Bug Reports / Feature Requests / Compute, and display, a HASH f...

Last post by FrankB - April 01, 2025, 05:53:39 AM

Hi Phil,

I have had a request to add a HASH function in ExifToolGUI:
https://github.com/FrankBijnen/ExifToolGui/issues/830

I think it is a valid request and could be useful. So I would like to add that in GUI. I looks like I can code computing a HASH (SHA-1, SHA-2, or MD5) quite easily in Delphi, no problems there. But I am wondering: Wouldn't it be a good addition for ExifTool to be able to compute a HASH of a file and display that as a 'pseudo'/'composite' tag?

Like Phil says, the prefix is a convenience to make it easier to read. The important thing is the namespace URI, and the prefix is simply shorthand for that namespace. The requirement is that the prefix be the same for all usage of the namespace in a specific document, not that it be the same in every system. The namespace must be the same across all systems to refer to the same schema.

Thank you for your reply.  I did not know if I could simply over-write the data in the image.  If I could add new data(i.e., new attributes) then maybe it would work.

At this point, at least now I know that EXIF V. 0230 doesn't support UTM coordinates.  One option down - many more to go.

This is a minor warning that may be ignored with the -m option.  It can happen if the image was edited by some other software that doesn't properly handle the preview.

oh, maybe the command did work to correct the date for all the items in the folder, but it's still returning this error for some reason

Ah, I am sorry.

Last post by igobythisname - March 31, 2025, 04:46:06 PM

I am trying to batch edit photos in a folder to update DateCreated to match Original Date;
i tested exiftool on a single photo and it was successful;
when i try to run the same command on the folder, it is telling me:

Code Select Expand

Warning: [minor] Error reading PreviewImage from file - (directory/IMGxxx.JPG)for all the files in that directory.

what am I doing wrong?

the command I'm using:
exiftool '-FileModifyDate<DateTimeOriginal' FileOrDir

I'm on macOS 14.7.4

thanks in advance!

Hi Layne,

This ExifTool config file allows you to convert GPS coordinates to UTM when reading from file.

...but where do you plan on storing them if you want to write them back to the file?  EXIF doesn't support UTM coordinates.  (MIE format does but there's not much support for that.)
