Looks like ApertureValue is F/FNumber. I think FNumber is more
popular. For example, from `identify -format '%[EXIF:*]' img.jpg`, I
only see FNumber=56/10 but no ApertureValue. This means the aperture
is F/5.6. (F is focal length here.)
The lens aperture. The unit is the APEX value.
The smallest F number of the lens. The unit is the APEX value.
Ordinarily it is given in the range of 00.00 to 99.99,
but it is not limited to this range.
It's great you add this. I'll try it if get some time.
