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. Supported formats are JPEG, Canon  CRW,  Canon  THM
       and  XMP	 sidecar  files.  Read-only support is currently available for
       JP2, PNG, PSD and TIFF format  and  includes  TIFF-based	 RAW  formats:
       Adobe  DNG,  Canon  CR2,	 Fujifilm RAF, Minolta MRW, Nikon NEF, Olympus
       ORF, Pentax PEF, Sony ARW and Sony SR2.

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.

OPTIONS
       -h     Display help and exit.

       -V     Show the program version and exit.

       -v     Be verbose during the program run.

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

       -u     Don't show unknown tags.

       -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)
	      t : interpreted (translated) Exif data (shortcut for -Pkyct)
	      v : plain Exif data values (shortcut for -Pxgnycv)
	      h : hexdump of the Exif data (shortcut for -Pxgnycsh)
	      i : IPTC data values
	      x : XMP properties
	      c : JPEG comment

       -P cols
	      Print columns for the  Exif  taglist  ('print'  action),	allows
	      detailed control of the print output. Valid are:
	      x : print a column with the tag value
	      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 modifier:
	      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 or IPTC 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 explicitely 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 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 -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.
