Removing Adobe Camera Raw Specific XMP Data

[Stephen Marsh]

Just curious about removing Adobe Camera Raw "development" related XMP info from a rendered file.

I have found the following in the forums:

Code Select Expand

exiftool -xmp:all=

However that is a little too broad as it appears to remove all XMP metadata, not just the Adobe Camera Raw data.

I was hoping to find an "ACR group" code rather than having to manually list every field, however one did not leap out at me looking at the TagNames reference.

I dumped all of the tags out of a file that had been processed with ACR and the relevant tags appear to be as follows:

Try this command :
exiftool -XMP:All -a -G1 -s FILE

That will give you the names of some of the actual XMP groups those tags belong to and if you're lucky, some of those groups might be able to be removed outright.   For example, on a random image I grabbed from Flickr, I found some of those History and Derived tags in XMP-xmpMM and many of the color adjustment ones in XMP-crs.  So the command to remove those whole blocks would be Exiftool -XMP-crs:all= -XMP-xmpMM:all= FileOrDir.

If you can't remove whole groups, you might look into creating a shortcut tag in a config file and you could use that to remove a bunch of individual tags.

Thank you StarGeek!

Thank you for the quick reply. Yes, that command is certainly more helpful in working out what the actual tags are!

It appears that the major "offending group" is just as you said:

[XMP-crs]

I presume that the crs is for Camera Raw Settings!

So you were bang on the money with:

Code Select Expand

exiftool -XMP-crs:all=

And I appreciate that there may be some other strays, however CRS was the major one that I was looking to remove.
