Adding/Writing CRS TAGs for Adobe Bridge/Photoshop Camera Raw.

[Philippe-Pierre]

Hello,
first, thank you for this very powerful EXIFtool!

Sorry, i am very new to EXIFtool but trying to add CRS related TAGs to a JPG file which does not have any at first.
Those TAGs values need to be read later through Adobe Bridge/Photoshop.
(that will be done via Applescript /shell script as follow :

Code Select Expand


do shell script (EXIFtool_path & " -XMP-crs:Highlights2012=-50 -XMP-crs:Shadows2012=30 -overwrite_original " & dst.JPG)

but my help request does not concern that part. Or does it? )

It "works", in a way, because TAGs are added to the dst.JPG file without problem but in a "format" that Adobe Bridge or Photoshop can't read them :
Here are the XMP raw Data excepts when done with :

What should I do to get closer to the Adobe XMP raw Data format?
Thank you for your time to read and your suggestions.

That is a question for Adobe, but my guess is that you may need to write all of the XMP-crs tags for them to be accepted by Adobe software.

You could figure this out yourself by manually editing the Adobe XMP to remove/change it until it stops working.

Thank you Phil for your answer.

Right, good guess. Sorry I forgot to say this at first : it works when importing XMP-crs tags from a source file that way :

Code Select Expand

" -TagsFromFile " & srcF " -XMP-crs:Highlights2012 -XMP-crs:Shadows2012 -overwrite_original " & dstF
But it imports much more than what we need and, again, in a different "format" compared to what Bridge does. Which might be a problem later in the "process chain"...

You could figure this out yourself by manually editing the Adobe XMP to remove/change it until it stops working.

Therefore thanks for your suggestion to make a wider tag selection to make it work, I will!
Best regards,
