NAME

       exiv2 - Image metadata manipulation tool

SYNOPSIS

       exiv2 [options] [action] file ...

DESCRIPTION

       exiv2  is  a program to read and write Exif, IPTC, XMP metadata and image comments and can
       read many vendor makernote tags. The program optionally converts between  Exif  tags,  XMP
       properties  and  IPTC datasets as recommended by the Exif Standard, the IPTC Standard, the
       XMP specification and Metadata Working Group guidelines.
       The following image formats are supported:

       Type   Exif         IPTC         XMP          Image comments

       · Support for GIF, TGA and BMP images is minimal: the image format is recognized,  a  MIME
         type assigned to it and the height and width of the image are determined.

       · Reading  other  TIFF-like RAW image formats, which are not listed in the table, may also
         work.

ACTIONS

       The action argument is only required if it is not clear from the options which  action  is
       implied.

       pr | print
              Print image metadata. This is the default action, i.e., the command exiv2 image.jpg
              will print a summary of the image Exif metadata.

       ex | extract
              Extract  metadata  to  *.exv,  XMP  sidecar  (*.xmp)  and  thumbnail  image  files.
              Modification commands can be applied on-the-fly.

       in | insert
              Insert  metadata from corresponding *.exv, XMP sidecar (*.xmp) and thumbnail files.
              Use option -S .suf to change the suffix of the input  files.  Since  files  of  any
              supported  format  can be used as input files, this command can be used to copy the
              metadata between files of different formats. Modification commands can  be  applied
              on-the-fly.

       rm | delete
              Delete image metadata from the files.

       ad | adjust
              Adjust  Exif  timestamps by the given time. Requires at least one of the options -a
              time, -Y yrs, -O mon or -D day.

       mo | modify
              Apply commands to modify (add, set, delete) the Exif,  IPTC  and  XMP  metadata  of
              image files. Requires option -c, -m or -M.

       mv | rename
              Rename  files  and/or  set  file timestamps according to the Exif create timestamp.
              Uses  the  value  of  tag   Exif.Photo.DateTimeOriginal   or,   if   not   present,
              Exif.Image.DateTime to determine the timestamp. The filename format can be set with
              -r fmt, timestamp options are -t and -T.

       fi | fixiso
              Copy the ISO setting from one of the proprietary Nikon or Canon makernote ISO  tags
              to  the  regular  Exif  ISO  tag, Exif.Photo.ISOSpeedRatings. Does not overwrite an
              existing standard Exif ISO tag.

       fc | fixcom
              Fix the character encoding of Exif Unicode  user  comments.   Decodes  the  comment
              using  the  auto-detected  or  specified  character  encoding and writes it back in
              UCS-2. Use option -n to specify the current encoding of the comment if necessary.

OPTIONS

       -h     Display help and exit.

       -V     Show the program version and exit.
              When -V is combined with -v (Verbose version),  build  information  is  printed  to
              standard  output  along with a list of shared libraries which have been loaded into
              memory. Verbose version is supported on Windows (MSVC, Cygwin  and  MinGW  builds),
              MacOSX and Linux and is provided for test and debugging.

       -v     Be verbose during the program run.

       -q     Silence  warnings  and error messages from the Exiv2 library during the program run
              (quiet). Note that options -v and -q can be used at the same time.

       -Q lvl Set the log-level to 'd'(ebug), 'i'(nfo), 'w'(arning), 'e'(rror) or  'm'(ute).  The
              default  log-level is 'w'. -Qm is equivalent to -q. All log messages are written to
              standard error.

       -b     Show large binary values (default is to suppress them).

       -u     Show unknown tags (default is to suppress tags which don't have a name).

       -g key Only keys which match the given key (grep).
              Multiple -g options can be used to grep info for several keys.   This  option  uses
              the  system  regular  expression  engine:  see man 3 regex.  Platforms which do not
              support regex use key for a substring match.  You can determine the availability of
              regex using the command: exiv2 -v -V -g have_regex

              exiv2 -g Date -pt R.jpg
              Exif.Image.DateTime           Ascii      20  2012:08:07 16:01:05
              Exif.Photo.DateTimeOriginal   Ascii      20  2011:09:18 16:25:48
              Exif.Photo.DateTimeDigitized  Ascii      20  2011:09:18 16:25:48

       -K key Only report data for given key.
              Multiple -K options can be used to report more than a single key.

              exiv2 -K Exif.Photo.DateTimeDigitized -K Exif.Photo.DateTimeOriginal -pt R.jpg
              Exif.Photo.DateTimeOriginal   Ascii      20  2011:09:18 16:25:48
              Exif.Photo.DateTimeDigitized  Ascii      20  2011:09:18 16:25:48

       -n enc Charset  to  use  to decode Exif Unicode user comments. enc is a name understood by
              iconv_open(3), e.g., 'UTF-8'.

       -k     Preserve file timestamps when updating files (keep). Can be used with  all  options
              which update files. The flag is ignored by read-only options.

       -t     Set  the  file  timestamp  according  to  the  Exif create timestamp in addition to
              renaming the file (overrides -k). This  option  is  only  used  with  the  'rename'
              action.

       -T     Only  set  the file timestamp according to the Exif create timestamp, do not rename
              the file (overrides -k). This option is only used with the 'rename'  action.  Note:
              On  Windows you may have to set the TZ environment variable for this option to work
              correctly.

       -f     Do not prompt before overwriting existing files (force overwrite).

       -F     Do not prompt before renaming files (Force rename). Appends '_1' ('_2', ...) to the
              name of the new file.

       -a time
              Time  adjustment  in  the format [-]HH[:MM[:SS]]. This option is only used with the
              'adjust' action. Examples: 1 adds one hour, 1:01 adds  one  hour  and  one  minute,
              -0:00:30 subtracts 30 seconds.

       -Y yrs Time adjustment by a positive or negative number of years, for the 'adjust' action.

       -O mon Time  adjustment  by  a  positive  or  negative  number of months, for the 'adjust'
              action.

       -D day Time adjustment by a positive or negative number of days, for the 'adjust' action.

       -p mode
              Print mode for the 'print' action. Possible modes are:
              s : print a summary of the Exif metadata (the default)
              a : print Exif, IPTC and XMP metadata (shortcut for -Pkyct)
              t : interpreted (translated) Exif tags (-PEkyct)
              v : plain Exif tag values (-PExgnycv)
              h : hexdump of the Exif data (-PExgnycsh)
              i : IPTC datasets (-PIkyct)
              x : XMP properties (-PXkyct)
              c : JPEG comment
              p : list available image previews, sorted by preview image size in pixels
              S : print image structure information (jpg, png and tiff only)
              X : print "raw" XMP (jpg, png and tiff only)

       -P flgs
              Print flags for fine control of the tag list ('print' action).  Allows  control  of
              the  type  of metadata as well as data columns included in the print output.  Valid
              flags are:
              E : include Exif tags in the list
              I : IPTC datasets
              X : XMP properties
              x : print a column with the tag number
              g : group name
              k : key
              l : tag label
              n : tag name
              y : type
              c : number of components (count)
              s : size in bytes
              v : plain data value
              t : interpreted (translated) data
              h : hexdump of the data

       -d tgt Delete target(s) for the 'delete' action. Possible targets are:
              a : all supported metadata (the default)
              e : Exif section
              t : Exif thumbnail only
              i : IPTC data
              x : XMP packet
              c : JPEG comment

       -i tgt Insert target(s) for the 'insert' action. Possible targets are the  same  as  those
              for the -d option, plus an optional modifier:

              X  :  Insert  metadata  from  an  XMP sidecar file <file>.xmp. The remaining insert
              targets determine what metadata to insert from the sidecar file. Possible are Exif,
              IPTC and XMP and the default is all of these. Note that the inserted XMP properties
              include those converted to Exif and IPTC.
              This is option is intended for "filter" operations on the XMP such as:
              $ exiv2 -e{tgt}- filename | xmllint .... | exiv2 -i{tgt}- filename

              Only JPEG thumbnails can be inserted (not TIFF thumbnails), they need to  be  named
              file-thumb.jpg.

       -e tgt Extract  target(s) for the 'extract' action. Possible targets are the same as those
              for the -d option, plus a target to  extract  preview  images  and  a  modifier  to
              generate an XMP sidecar file:
              p[<n>[,<m>  ...]]  :  Extract  preview images. The optional comma separated list of
              preview image numbers is used to determine which preview  images  to  extract.  The
              available  preview  images  and their numbers are displayed with the 'print' option
              -pp.

              X : Extract metadata to an XMP  sidecar  file  <file>.xmp.  The  remaining  extract
              targets  determine what metadata to extract to the sidecar file. Possible are Exif,
              IPTC and XMP and the default is all of these.

              - : Output sidecar file to stdout (see -i tgt for example)

       -r fmt Filename format for the 'rename' action. The format string follows strftime(3)  and
              supports the following keywords:
              :basename:   - original filename without extension
              :dirname:    - name of the directory holding the original file
              :parentname: - name of parent directory
              Default filename format is %Y%m%d_%H%M%S.

       -c txt JPEG  comment string to set in the image ('modify' action). This option can also be
              used with the 'extract' and 'insert' actions to modify metadata on-the-fly.

       -m file
              Command file for the 'modify' action.  This  option  can  also  be  used  with  the
              'extract' and 'insert' actions to modify metadata on-the-fly.

       -M cmd Command  line  for  the  'modify'  action.  This  option  can also be used with the
              'extract' and 'insert' actions to modify metadata on-the-fly.  The format  for  the
              commands is the same as that of the lines of a command file.

       -l dir Location (directory) for files to be inserted or extracted.

       -S .suf
              Use suffix .suf for source files in 'insert' action.

COMMANDS

       Commands for the 'modify' action can be read from a command file, e.g.,

          exiv2 -m cmd.txt image.jpg

       or given on the command line, as in

          exiv2 -M"add Iptc.Application2.Credit String Mr. Smith" image.jpg

       Note  the  quotes.  Multiple  -m  and  -M  options can be combined, and a non-standard XMP
       namespace registered.

          exiv2 -M"reg myprefix http://ns.myprefix.me/" -M"add Xmp.myprefix.Whom Mr. Smith" -M"set Exif.Image.Artist Mr. Smith" image.jpg

       When writing Exif,  IPTC  and  XMP  metadata,  exiv2  enforces  only  a  correct  metadata
       structure.  It  is  possible  to  write  tags  with  types and values different from those
       specified in the standards, duplicate Exif tags, undefined tags, or  incomplete  metadata.
       While  exiv2  is  able  to  read  all  metadata that it can write, other programs may have
       difficulties with images that contain non standard-conforming metadata.

   Command format
       The format of a command is

       set | add | del key [[type] value]

       set    Set the value of an existing tag with a matching key or add the tag.

       add    Add a tag (unless key is a non-repeatable  IPTC  key;  nothing  prevents  you  from
              adding duplicate Exif tags).

       del    Delete all occurrences of a tag (requires only a key).

       key    Exiv2 Exif, IPTC or XMP key.

       type   Byte  |  Ascii | Short | Long | Rational | Undefined | SShort | SLong | SRational |
              Comment for Exif keys,
              String | Date | Time | Short | Undefined for IPTC keys, and
              XmpText | XmpAlt | XmpBag | XmpSeq | LangAlt for XMP keys.

              A default type is used if none is explicitly given. The default is determined based
              on key.

       value  The  remaining  text  on  the  line  is the value. It can optionally be enclosed in
              single quotes ('value') or double quotes ("value").

              The value is optional. Not providing any value is equivalent to an empty value ("")
              and is mainly useful to create an XMP array property, e.g., a bag.

              The format of Exif Comment values includes an optional charset specification at the
              beginning:
              [charset=Ascii|Jis|Unicode|Undefined ]comment

              Undefined is used by default if the value doesn't start with a charset definition.

              The format for an IPTC Date value is:
                  YYYY-MM-DD (year, month, day)

              The format for an IPTC Time value is:
                  HH:MM:SS (hours, minutes, seconds)
              and may optionally be followed by:
                 -HH:MM or +HH:MM (hours, minutes ahead/behind UTC)

              The format of Rational (and SRational) is one of:
                  integer
                  integer-numerator/integer-denominator
                  Fnumber
                  fnumber

              Rational Examples:
                  exiv2 "-Mset Exif.Photo.MaxApertureValue 557429/62500" X.jpg
                  exiv2 "-Mset Exif.Photo.MaxApertureValue F5.6" X.jpg

              The Rational format Fnumber (or fnumber) is for the convenience of setting aperture
              values.  Aperture values are stored in Exif is an APEX value which can be evaluated
              by the expression:

                  apex-value  =    log(Fnumber) * 2.0 / log(2.0)
                  Fnumber     = exp(apex-value * log(2.0) / 2.0)

              The Rational format Fnumber is valid for any Rational, even when the key is not  an
              Aperture.     More    information    about    APEX   value   is   available   from:
              http://en.wikipedia.org/wiki/APEX_system

              The format of XMP LangAlt values includes an optional language qualifier:
              lang="language-code" text

              lang="x-default" is used if the value doesn't start with a language qualifier.

                  exiv2 -M'set Xmp.dc.title lang="de-DE" Euros' X.jpg
                  exiv2 -M'set Xmp.dc.title lang="en-GB" Pounds' X.jpg
                  exiv2 -M'set Xmp.dc.title lang="en-US" In God We Trust' X.jpg
                  exiv2 -M'set Xmp.dc.title All others pay cash' X.jpg

              To remove a language specification, set the value to '' (empty string)
                  exiv2 -M'set Xmp.dc.title lang="en-US"' X.jpg

              To remove all language specifications, delete the key:
                  exiv2 -M'del Xmp.dc.title' X.jpg

       To register additional XMP namespaces, combine the command with:

       reg prefix namespace

   Command file format
       Empty lines and lines starting with # in a command file are ignored (comments).  Remaining
       lines are commands as described above.

EXAMPLES

       exiv2 *.jpg
              Prints a summary of the Exif information for all JPEG files in the directory.

       exiv2 -pi image.jpg
              Prints the IPTC metadata of the image.

       exiv2 rename img_1234.jpg
              Renames img_1234.jpg (taken on 13-Nov-05 at 22:58:31) to 20051113_225831.jpg

       exiv2 -r':basename:_%Y%m' rename img_1234.jpg
              Renames img_1234.jpg to img_1234_200511.jpg

       exiv2 -et img1.jpg img2.jpg
              Extracts   the   Exif  thumbnails  from  the  two  files  into  img1-thumb.jpg  and
              img2-thumb.jpg.

       exiv2 -it img1.jpg img2.jpg
              Inserts (copies) metadata from img1.exv to img1.jpg and from img2.exv to img2.jpg.

       exiv2 -ep1,2 image.jpg
              Extracts previews 1 and 2 from  the  image  to  the  files  image-preview1.jpg  and
              image-preview2.jpg.

       exiv2 -eiX image.jpg
              Extracts  IPTC  datasets  into  an  XMP  sidecar  file image.xmp and in the process
              converts them to "IPTC Core" XMP schema.

       exiv2 -iixX image.jpg
              Inserts IPTC and XMP metadata from an XMP sidecar file  image.xmp  into  image.jpg.
              The  resulting  IPTC  datasets  are  converted  from  the  "IPTC  Core"  XMP schema
              properties in the sidecar file to the older IPTC  IIM4  format.  The  inserted  XMP
              properties include those in the "IPTC Core" XMP schema.

       exiv2 -M"set Exif.Photo.UserComment charset=Ascii New Exif comment" image.jpg
              Sets the Exif comment to an ASCII string.

       exiv2 -M"set Exif.GPSInfo.GPSLatitude 4/1 15/1 33/1" \
              -M"set Exif.GPSInfo.GPSLatitudeRef N" image.jpg
              Sets  the latitude to 4 degrees, 15 minutes and 33 seconds north. The Exif standard
              stipulates that the GPSLatitude tag consists of  three  Rational  numbers  for  the
              degrees, minutes and seconds of the latitude and GPSLatitudeRef contains either 'N'
              or 'S' for north or south latitude respectively.

       exiv2 insert -l/tmp -S.CRW /data/*.JPG
              Copy all metadata  from  CRW  files  in  the  /tmp  directory  to  JPG  files  with
              corresponding  basenames  in the /data directory. Note that this copies metadata as
              is, without any modifications to adapt it to the requirements of the target format.
              Some tags copied like this may not make sense in the target image.
