I have the feeling that the ShutterSpeedValue (0x9201) is reporting the value of the ExposureTime (0x829A)

Hi Henry,
ExifTool converts both ShutterSpeedValue and ApertureValue to the same units as ExposureTime and FNumber respectively to facilitate easy copying between these tags. See the EXIF tags documentation (https://exiftool.org/TagNames/EXIF.html) for details.

Hi Phil,
I have attached two text files that were reported on the same JPG file. The only difference is that in the second file the verbose option is on. The syntax:
1: -- %EXIFTool% -a -u -g1 %filename% > c:\temp\exiftooloutput.txt
2: -- %EXIFTool% -a -u -g1 -v %filename% > c:\temp\exiftoolverboseoutput.txt
If you look in the first file, a value of 1/40 is reported for both Exposure Time and for Shutter Speed Value
In the second file, a value of 1/40 is reported for Exposure Time, but 5.322274882 (1123/211) for Shutter Speed Value. This is the correct value.
Best regards,
Henry
Like I said, the value of 1123/211 is converted by ExifTool to seconds for your convenience.
