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   -
       CRW    Read/Write   -		-	     Read/Write
       MRW    Read	   Read 	Read	     -
       TIFF   Read/Write   Read/Write	Read/Write   -

       PNG    Read/Write   Read/Write	Read/Write   Read/Write
       PGF    Read/Write   Read/Write	Read/Write   Read/Write
       RAF    Read	   Read 	Read	     -
       EPS    - 	   -		Read/Write   -
       XMP    - 	   -		Read/Write   -
       GIF    - 	   -		-	     -
       PSD    Read/Write   Read/Write	Read/Write   -
       TGA    - 	   -		-	     -
       BMP    - 	   -		-	     -
       JP2    Read/Write   Read/Write	Read/Write   -

       o 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.

       o 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 encod-
	      ing 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.

       -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 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 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

       -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 pre-
	      view 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 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.

       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 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 Coordinated 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-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.
