Analyzing various EXIF data, one noticed there are several date and time data inside. [File] from what I understand is system data, just displayed there for convenience, not really part of EXIF data (somebody correct me if I'm wrong on any of this). While [EXIF] and [Composite] is true EXIF data.
Can somebody give a short explanation when each of these is created and when each of these is changed?
For example, what is the usefulness of File Access Date/Time? Which one would be a good reference to take for sorting photos by their shooting time? [EXIF] group Create Date or [Composite] group Create Date?
