I'm using exiftool 9.32 and I was wondering if there was a way to extract the Apex values from the metadata. When I run

exiftool  -s -H -sort

I get

0x9202 ApertureValue                   : 1.4

When I use ExifChanger on the Mac (which wraps exiftool 9.18), I see the Apex value, 0.970853978431944.

I'd like to understand how to get the Apex value out.

The only way to do this currently is with the -v option.  But this will show all tags whether you want to see them or not.  If you are on Mac/Linux, you can do this:

exiftool -v FILE | grep ApertureValue

This will also show the components of the EXIF rational value, which is how the value is stored.  If you want to see the binary value too, use -v3 (but the "grep" won't work to find this).

...where DIR is the name of a directory/folder containing the images.  On Mac/Linux/PowerShell, use single quotes (') instead of double quotes (") around arguments containing a dollar sign ($).
