exif-date
Svein Hamnes Aaberge
display-program they are sometimes (like in f-spot) placed when it was last
modified instead of when the picture was shoot. I know this is probably not
possible with gimp, but do anyone know how to put in exif-data in a picture
that do not have it (gexif will let me edit exif-data, but will not open
when there is no exif-data). If that is not possible, is there somehow to
change the last modified date so I get it equal to the date the picture was
shoot?

jhead <http://www.sentex.net/~mwandel/jhead/> will let you read,
manipulate, copy, delete and transfer EXIF data in and between files.

Thank you. I used jhead -te"dscf0461.jpg" dscf0463.jpg
to make an exif-file on my image and then modified it with gexif. I couldn't
find an option to just add date in jhead. I tried :"jhead
-ts2003:10:01-12:00:00 dscf0463.jpg", but got the output:"File
'dscf0463.jpg' contains no Exif timestamp to change". Maybe you know
another option? Under shortcommings on the web-page it says that "There is
also no way to create minimal exif headers". So I guess I have to still
modify with gexif and just add a comment that the exif-data is transfered?

If the JPEG doesn't contain any exif-data to begin with then I suppose
all you can do is copy one from another file then modify the copied
timestamp. You can't modify what isn't there.
I've never used gexif, could you modify an exif header with it to just
be some generic info for your files, then copy that to all of them and
datestamp them afterwards?

I'm not sure what you mean. gexif open the exifdata and you can edit all the
information line for line, then save it. There is also an add-possibility
and remove-possibility. So I guess you can make a minimal exif with it
(using the remove possibility) and then copy the information to all other
files missing exif with jhead, then open the individual files with gexif,
and add date and time.

That's fine up to the last bit. You should be able to set the timestamp
using jhead with -ts (and thus save having to load the files into
another program again) once they have an exif header to work on. You
should only need to use gexif once to get your 'template' exif-header to
copy to all the other files, then jhead to copy and timestamp.
This is assuming that the only thing you want to be unique in each file
is the timestamp.

Thank you. That's exactly what I wanted.

If you have perl, exiftool is a MUCH MUCH better program:

Unlike jhead, exiftool actually can cope with getting the MakerNotes correct
when doing such copying. Jhead is rather simple minded in how it copies the
data.

Thank you. I don't have time to look into it today, but I sure will. I
didn't have it in my distribution (SuSE 9.2), so I hope the compiling will
go well.
