I have used the ExifTool GUI for geotagging of my Canon RAW Files (CR2). But now I got a new camera, which produces CR3 Files and this format isn't supported. What can I do?
What version of Exiftool (not ExiftoolGUI) are you using? Recent versions do have support of .CR3 files.
With the current version I gave it a try: it works! Thank you.
