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 produce, 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 default 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 additional information about the camera  or
       image not part of the Exif standard.  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 engineering (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     specification,     revision     6.0
       (http://partners.adobe.com/asn/developer/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 referencing 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/Computer/Digicams/exif-e.html)  and  its contributers.  Minolta maker
       note support was contributed by Javier Crespo <jcrespoc@dsland.org>.  Panasonic maker  note  support  was
       contributed by Tom Hughes <tom@compton.nu>.
