I was looking at the file formats for which ExifTool provides R/W support the other day and wondered if there are any limitations when it comes to writing EXIF, IPTC or XMP tags to camera raw files. Can I theoretically inject any tag into a CRW file for example, or are there certain limits (like writing to file only allowed for tags that make sense to change)?
Thx

Hi Uwe,
Most RAW images are based on the TIFF format, so the same rules apply as for TIFF images.
CRW is a notable exception though, and only supports native CIFF and XMP information (the Canon utilities should be able to read this XMP, but I would be surprised if any 3rd party apps are able to).

Hi Phil
Thanks for the info. I was aware of the CIFF format, but not sure about the usage of XMP with it.
Keep up the excellent work!
