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

       JP2    Read/Write   Read/Write   Read/Write   -

       • 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.
