Writing IPTC in Canon CR2 RAW
Posted: Sat May 28, 2022 10:38 am
I have been using ExifToolGUI successfully for ages writing GPS and various fields into RAW files.
A few minutes ago, just to see what would happen, I used the XnView IPTC Editor to write one of my templates into a test CR2 RAW file.
It took a couple seconds longer for it to do it's thing as compared to writing to a jpeg; however, it seems to have worked.
I can see/read the IPTC in XnView and I can also view it in ExifToolGUI.
The information is contained within the file; no sidecar.
I have not yet created a jpeg from the RAW file to check the outcome.
I have searched this and am more confused after searching than I was before.
Is it okay practice to write IPTC, XMP, and Keyword Tags into RAW files ?
Will it corrupt the picture data?
Thanks.
