When I run ExifTool GUI on a folder which contains Canon cr3 files from my EOS R, it will show the cr3 files in the filelist tab, including a preview and exif info etc. But, if I switch to the chart tab in the same folder there are not any files shown, regardless of which type of chart I select. Of course, if there are jpegs or tiffs in that folder it will show those in the resulting charts, but not cr3 files. Even if I choose "All" in the file type, it still doesn't reflect cr3 files in the result. Therefore, if the folder only has cr3 files, it does not generate a chart.
I am using Windows 11 and can view the cr3 files in Windows Explorer, including previews so I have the codec installed.
Any help would be greatly appreciated.
As per the stickied thread (https://exiftool.org/forum/index.php?topic=4553.0) in this sub forum, the Exiftool GUI hasn't had support from its author in about a decade.
