Thanks for making the great tool. Our application (self hosting photo cloud) adds one customized exif tag "com.lomorage.originhash", and seems like it can be recognized as `"ComLomorageOriginhash": "b12fb8a5bb04738efe66f186a45f0388d8fabff1"` at version 11.88 (ubuntu focal)

$ exiftool -ver
11.88
$ exiftool -j slow_motion.mov | grep Lomo
  "ComLomorageOriginhash": "b12fb8a5bb04738efe66f186a45f0388d8fabff1",

but parsed as `LomorageOriginhash              : b12fb8a5bb04738efe66f186a45f0388d8fabff1` at version 12.05 (ubuntu groovy)

# exiftool -ver
12.05
# exiftool -j  slow_motion.mov | grep Lomo
  "LomorageOriginhash": "b12fb8a5bb04738efe66f186a45f0388d8fabff1",

So can you please the right command to get ComLomorageOriginhash tag name?

Thanks again for helping.

Yes:

July 27, 2020 - Version 12.02
  - Removed "Com" from the start of some unknown ItemList tag names


Previous versions already removed "ComAppleQuicktime", but not other "Com" prefixes.  The change was made because some tag names were getting too long.

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

Thanks for quick reply. I should have read the release note more carefully, and will add change at our side.
