Reading unknown MakerNotes tags on the command line
« on: April 11, 2014, 04:51:58 PM »
I'm inspecting many of my photos to maybe discover the meaning of unknown MakerNotes tags, and would like to browse quickly a specific set of unknown tags in many photos. I've tried like:

Code: [Select]
$ exiftool -Panasonic0x87 a.jpg
$ exiftool -Panasonic0x0087 a.jpg
$ exiftool -tag0x0087 a.jpg
$ exiftool -tag_0x0087 a.jpg
$ exiftool -Unknown_0x0087 a.jpg
$ exiftool -MakerNotes:0x0087 a.jpg
$ exiftool -MakerNotes:0x87 a.jpg

... but none worked  :(

Is their a way to specify a specific unknown MakerNotes tag on the command line? I can probably come up with grep command to process the output of all tags, but would prefer to use ExifTool directly if possible.

You can only access unknown tags if you specify -u or -U.  Use -s with -u to see the names of the unknown tags.

...where DIR is the name of a directory/folder containing the images.  On Mac/Linux, use single quotes (') instead of double quotes (") around arguments containing a dollar sign ($).

Great thanks, it works! My attempt #2 was very close, just missing an underscore.

For reference, example command line to see an unknown MakerNotes tag value for all files in a directory:
Code: [Select]
$ exiftool -u -Panasonic_0x0087 *.JPG
