hi; sorry for my bad english or typos

i am searching for a command line tool that allows to change exif properties
within a large amount of images in a directory and also in subdirectories.

something like

exifchg abc??.* /s -artist My Name -cright (c) 2004 Dick Tom and
Harry -authcomm please contact me at www.tomdickandharry.ext

for changing exif attributes ...

or like

exifchg abc??.* -v -artist >file

for viewing and saving "artist" exif attribute in a file ...


does it exist something like that?

I believe exif utils (http://www.hugsan.com/EXIFutils/) will do this.
This is shareware, but the free version which has a restricted set of
features can be used (legally) for an unlimited time. I'm not sure
what the restrictions actually are, so you'll need to check this out
to see if it will do what you want to do.

Why do you want a command line tool? If you want to write batch files
or something, you need something like above. If you just want to be
able to work on many images and images within subdirectories, Exifer
is a GUI tool that can change exif properties on a large number of
images in a directory, and also in subdirectories.

Exifer is a great tool, wit a big but....

If you are also using IPTC* information, besides exif information, you can
get into trouble, as uses a non-standard IPTC header, resulting in quite a
few programs not being able to read it, including the big ones, such as
Adbobe Photoshop. and irfanview. If you dont use IPTC information, or only
for your own use, It is not that big of a problem, as long as you are aware
of it

* IPTC is a way to incluse information (Caption, Copyright information,
keywords, and even a complete story. IPTC has been developed by the (IIRC)
American Press Organisation, ta be able to quickly send photo's and text
over a line, so both sory and text were not send seperated, so editors could
save a lot of time sorting things out. Today, IPTC is widly used by misc
paper/magazine/press organisations world wide

A nice Shell extention is IPTC EXT
(http://photothumb.com/IPTCExt/index.shtml) just install and ask the
properties for any JPG file

An other, nice Explorer (filemanager) extention is PixVue
(http://www.pixvue.com/), Witch dies the same, but only in the filesmanager.

Both XNView and Irfanview also have IPTC reading and writing options.

As said, exifer does too, even more extended, but it cannot be read by a,ll
applications.

i looked for these functions in acdsee but i am not able to change exif
information in multiple files and i haven't seen this iptc ... with acdsee 5

is it possible that irfan does the work better? :)

iptc is a problem also with that exifutils?

sorry for the following question but... shell extension IS commandline or is
context-menu / rightclick menu?

thanks

Irfan view does comply to the standards set by the Amercian Press
Association
But it does not let you alter IPTC data batch wise, but then again, I did
not found any other freeware program, besides exifer (who has the already
described problem of being non standard) that could to IPTC batchwise.

TPIC and Exif Wise, ACDsee 6 is no differtent over ACDSee 5.

I found That XNView does have a nice batch mode for IPTC/EXIF data.

Coould be a real timesaver si you have lots of pictures to edit.

I'm not sure where you got this idea from, but Exifer modified files
can be read in Irfanview without problems. I just tested it to be
sure. I used Exifer to modify the IPTC data of a file, then opened it
in Irfanview. Irfanview opened the file and had no problem displaying
the EXIF and (modified) IPTC data.

There are a few programs (eg, Thumbs+, PhotoThumb) that have problems
with the EXIF (not IPTC) data in an Exifer modifed file. This is
because those programs do not correctly read the data, *not* because
Exifer writes in some non-standard way. This is also because Exifer
maintains the "Maker notes" (the custom fields each camera
manufacturer adds to the EXIF data), while most other programs that
can modify EXIF data lose the maker notes when they save. See the
Exifer home page for details.

To the OP - Irfanview does not do batch EXIF editing, so is not really
suitable. Exifer does do batch editing, and the files it writes can be
read by Irfanview and almost all other programs without problems.

You edited the thread incorrectly. MightyKitten was talking about
Exifer, not EXIFUtils. I am not a EXIFUtils user, so I don't know for
sure whether there is a problem, but I doubt it, since EXIFUtils can
read IPTC information, but not change it.

In any case, MightyKitten's report of problems with Exifer is false.
There is no problem with Exifer writing a file and Irfanview reading
it. See my other post in this thread.

Shell extension means context-menu/right click.

ExifUtils is a command-line tool.

Your right Terry,

As it indeed seems, I am unable to recreate the problems I had. It might
have been a simple answer of rebooting the system (since I hadn't done this
after intstalling exifer). All Apps I know of having 'standard' iptc data
are registering exif's data right. Therefor I will have to take back my
suggestions about a non standard format for exifer.

As for using irfanview: each his/her own taste. IMHO it is to 'hidden' in
irfanview, and I realy like the CTRL+E option in exifer to edit the date
(mostly since I still have 10.000+ photo's to do) For now, I switched to XN
view for editing (batch editing aviable) until I am absolute sure about not
creating unnesseccairy problems with exifer. (probably will run some more
tests)

sorry, i tried to divide the two questions.
this one is about exif utils and not about exifer.

thanks for all the answers :)

Mapivi (http://mapivi.de.vu) is able to do some IPTC batch processing.
