EXIFTAGS(1)		    General Commands Manual		   EXIFTAGS(1)

NAME
       exiftags	- output the properties	contained in a JPEG Exif section

SYNOPSIS
       exiftags	[ -acdilquv ] [	-s delim ] [ file ...  ]

DESCRIPTION
       The  exiftags  utility  parses file or, by default, its standard	input,
       looking for a JPEG APP1 section	containing  Exif  (Exchangeable	 Image
       File) data.  The	properties contained in	these data are then printed to
       the standard output.

       Digital cameras typically add Exif data to the image  files  they  pro-
       duce, containing	information about the camera and digitized image.  The
       options described below may be used to  control	output	verbosity  and
       section formatting.

OPTIONS
       -a     Output  camera-specific,	image-specific,	and verbose properties
	      contained	in the file.

       -c     Output camera-specific properties	contained in the file.

       -d     Output Exif parse	debug information.

       -i     Output image-specific properties contained in the	file.

       -l     Make lens	characteristics	image-specific.	 Useful	for higher-end
	      cameras  that have removable lenses (i.e., not "point-and-shoot"
	      cameras).

       -q     Suppress output of a property section header.

       -s     Separate field name and value with the string  delim.   The  de-
	      fault is ': '.

       -u     Output  unknown or unsupported properties	contained in the file.
	      Also, output invalid properties when  debugging  information  is
	      requested.

       -v     Output verbose properties	contained in the file.

MAKER NOTES
       Some  camera  manufacturers  include  a "maker note" section with addi-
       tional information about	the camera or image not	part of	the Exif stan-
       dard.   The format of these maker notes varies wildly and manufacturers
       are not forthcoming with	implementation details.	  Therefore,  exiftags
       maker  note  support is the result of experimentation and reverse engi-
       neering (see below for credits) and incomplete.	exiftags is  known  to
       have  at	 least	partial	support	for the	following manufacturers' maker
       notes:

	   Asahi/Pentax
	   Canon
	   Casio
	   Fujifilm
	   Leica
	   Minolta
	   Nikon
	   Olympus
	   Panasonic
	   Sanyo
	   Sigma

       If you wish support for additional  manufacturers  or  cameras,	please
       send  any  information  you  have about the data	format or, better yet,
       patches,	and a sample image file	to the author.	(Though	 he  makes  no
       promises.)

DIAGNOSTICS
       The exiftags utility exits 0 on success,	and >0 if an error occurs.

STANDARDS
       The  exiftags utility was developed using the 2003 draft	Exif standard,
       version 2.21 (http://tsc.jeita.or.jp/) and the June 1992	TIFF  specifi-
       cation,	    revision	 6.0	 (http://partners.adobe.com/asn/devel-
       oper/pdfs/tn/TIFF6.pdf).

BUGS
       Not all Exif 2.21 properties are	supported, due either to the  author's
       laziness	 or  incomplete	information.  Maker note support is spotty due
       to lack of information.

AUTHOR
       The exiftags utility and	this man page were written by Eric M. Johnston
       <emj@postal.net>.   Portions of the utility were	developed while	refer-
       encing the public domain	Jhead utility, version 1.2, by Matthias	Wandel
       <mwandel@rim.net>.   Some  maker	note support is	the result of TsuruZoh
       Tachibanaya's	compendium    (http://www.ba.wakwak.com/~tsuruzoh/Com-
       puter/Digicams/exif-e.html)  and	 its contributers.  Minolta maker note
       support was contributed by Javier Crespo	<jcrespoc@dsland.org>.	 Pana-
       sonic  maker  note  support  was	 contributed  by Tom Hughes <tom@comp-
       ton.nu>.
