EXIF Packet Structure

If an EXIF packet is supplied it will include any relevant tags it can understand. The "tag numbers" used in EXIF are used directly to encode the field numbers, so unknown fields can be referenced from the EXIF specification. The following is some of the more common fields.

The EXIF structure is not designed to return ALL information available, you should use external applications if you wish to fully analyse the contents

Field #	Field Name	Exif Tag	Description
f271	Make	01:0f	Make
f272	Model	01:10	Model
f306	ModDt	01:32	Modification date/time
f33432	Copyright	82:98	Copyright information
