Property Value
Nullable (boxed) ImageGear.Core.ImGearRationalUInt structure value.This property accesses the MaxApertureValue tag. The tag specifies 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.
Get accessor returns the tag value if the tag is present in the metadata tree, or null otherwise.
Set accessor replaces the current tag value if the tag is present in the metadata tree, adds the tag if it was not present, or deletes the tag if a null value is passed.
See the EXIF 2.2 specification for tag usage details.
