Detailed Description

Table giving information about each EXIF tag.

There may be more than one entry with the same tag value because some tags have different meanings depending on the IFD in which they appear. When there are such duplicate entries, there must be no overlap in their support levels. The entries MUST be sorted in tag order. The name and title are mandatory, but the description may be an empty string. None of the entries may be NULL except the final array terminator.
