    As far as I can tell, XMP's are always created. There is an option for Sidecars in the On1 settings, I don't think it affects XMP but you can verify that it is on.

    I assume you're looking for these XMP's in Explorer since you won't see them from inside Photo Raw.

    rick,

    i did some testing now, i used one DNG, one JPG and one RAW file. On all tree of them i wrote some metadata. then i checked in my explorer as you assumed and now i see that for the DNG and the JPG PR made only a .on1 file. For the RAW file PR created a .xmp AND a .on1 file. i thought it would be a .xmp for everyone of them.

    The Setting for sidecars was enabled.

    Try using the Embed Metadata command for the .dng and .jpg files. That should force an .xmp to be written.

    ok brian, found it, as i read there that metadata could not be written in video or raw files, so that's why i got an xmp for the raw image. i think that in my dng and jpg the metadata automaticly was embedded by PR. could this be right?

    Only if you've chosen to save the metadata when exporting those files.

    Here's what the User Guide says about the Remove Unmanaged XMP option:

    When checked, the Remove Unmanaged XMP button only exports metadata that is represented in Photo RAW’s Metadata pane; any other unmanaged image metadata from other apps will not be included.

    ok, here i'm back again with a question about my metadata. i have a bunch of jpeg where i put keywords in. so now my keyword list has become big. now when i export an image and i open it with xnview MP, i select the image with my right button and select "edit iptc". there i select "keywords" and in the window up i see the keywords i gave to the picture in PR, but when i select the window below "categories database" i see all the keywords from my PR keyword list, even those who don't belong to this picture. i want that any user can see my keywords i gave to the picture but not my whole keyword list. is there anyway to prevent this?

    Can you show us an example of what you're asking about? The program does not put your entire keyword list into the photos or their sidecar files. It only add those keywords which have been added to that photo. You can verify this by opening the sidecar(s) or even the photo itself if it can hold embedded keywords in a text editor. You'll see the keywords which have been saved with that photo in clear ASCII text.

    Is it possible that XnView is assembling its own list of keywords you've used the same way the Photo RAW does and what you are viewing is the program's list and not anything associated with a specific image?

    hi brian,

    i'l try to explain

    here is the keyword list of PR, as you see i wrote lille and vacation in the keyword window, below is my keyword list

     And here is my xnview mp window, as you see above are the two words i put in the keyword window, but below i can read my keyword list from PR.  i hope you understand what i mean now? txs

    I understood the question; I guess I didn't explain myself very well.

    I'm not familiar with XnView but I'm betting that like all DAMs it builds and saves its own list of keywords from the keywords it sees in the photos it manages. Unfortunately, the screenshot is too low resolution for me to read the UI. Thanks for including them all the same. I seriously doubt that all of those keywords are embedded into that single image you are currently viewing. I think it's a .jpg? Open it in Window's default image view app and look at what it actually contains there. That is all that other viewers will see.

    Again, you can verify this for yourself by opening the image file in a file viewer, one that lets you see the actual uninterpreted data in the file. A good text editor will do this. You'll see the metadata in plain, readable, ASCII text and you'll be able to see if the entire keyword list from Photo RAW has been embedded or not.

    If you'll post your .jpg somewhere I can download it I'll be glad to take a look at it and confirm what it actually contains.

    brian,

    take a look here

    maybe it is not in the photo, but PR stores the keyword list somewhere where xnview can read it???

    No, XnView is not reading Photo RAW's keyword list. It is stored inside an encrypted database. I can't even read them outside of the program and I've tried! 😁

    The only keywords embedded in that .jpg are the 2 you've assigned — vacation and lille. You can see in my screenshot below that's all that is being shown in both the Finder and in Preview.

    I'm assuming the XnView allows you to find photos by searching the keyword list the same way that Photo RAW and all other DAMs do. In order to do that it has to keep a list of all the keywords used in all the photos it manages. It builds that list itself from the keywords it sees in the photos you view with it. If I sent you one of my photos and you looked at it with XnView, you'd find my keywords have been added to that list and that list is visible when viewing my photo. Obviously, my photo would not contain a list of your keywords, right? If I had opened your .jpg in Photo RAW, your keywords would have been added to my Keyword List as well. I regularly have to clean out keywords from photos I've worked on for other users here. It's just how DAMs work.

    ok brian i understand. i'm sure you're right that xnview is building it's own DB. but now i am reassured that no one else can read my list. thank you for checking this.

    bye

    Marc
