NAME
       exiv2 - Image metadata manipulation tool

SYNOPSIS
       exiv2 [options] [action] file ...

DESCRIPTION
       exiv2  is a program to read and write Exif, IPTC and XMP image metadata
       and image comments. The following image formats are supported:

       Type   Exif	   IPTC		XMP	     Image comments
       ─────────────────────────────────────────────────────────────
       JPEG   Read/Write   Read/Write	Read/Write   Read/Write
       EXV    Read/Write   Read/Write	Read/Write   Read/Write
       CR2    Read/Write   Read/Write	Read/Write   -

       EPS    -		   -		Read/Write   -
       XMP    -		   -		Read/Write   -
       GIF    -		   -		-	     -

       BMP    -		   -		-	     -
       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 com‐
	      mand  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.DateTimeOrig‐
	      inal 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 stan‐
	      dard Exif ISO tag.

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

OPTIONS
       -h     Display help and exit.

       -V     Show the program version and exit.

       -v     Be verbose during the program run.

       -q     Silence warnings and error messages from the Exiv2 library  dur‐
	      ing  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  output info for this Exiv2 key (grep). Multiple -g options
	      can be used to grep info for several keys.

       -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 time‐
	      stamp, 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 over‐
	      write).

       -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 sec‐
	      onds.

       -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

       -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 a 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.
	      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.

       -r fmt Filename format for the 'rename' action. The format string  fol‐
	      lows 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.

       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 pre‐
	      vents 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	IPTC  Date  values is YYYY-MM-DD (year, month,
	      day), that for  IPTC  Time  values  is  HH:MM:SS+|-HH:MM,	 where
	      HH:MM:SS	refers	to local hour, minute and seconds and +|-HH:MM
	      refers to hours and minutes ahead or  behind  Universal  Coordi‐
	      nated Time (+|- means either a + or a - sign is required).

	      The  format  of XMP LangAlt values includes an optional language
	      qualifier:

	      [lang=language-code ]text

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

       An additional command is available to register XMP namespaces:

       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-pre‐
	      view1.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.
