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>.
