JPG-comments, EXIF- and IPTC-metadata

[LeLampiste]

Good evening
I've read carefully this forum to find a very simple answer : where should I install exiv2.exe and its dll ?
I've try this plugin that works fine except that I'm completely unable to modify an exif parameter (here, the creation date to be able to synchronize my pictures with those of my wife when we have some minutes of difference)
Looking in the src, I thought that a sub directory could work better than the rrot of the plugin, but no.

By the way, it could be a good suggestion to develop, with exif, a function able to shift a batch of pictures by a certain amount of time - exif.date I mean because, for the date of the file, it already exists.
You already did a good job. Go on.

This is up to you

Well this is the way I do the changes:
I use the jpg comment plugin

First change the file date to the correct value (using Add Time)
Next set the exif value according to the file date:

- Select all file to be changed at TC
- Choose "Files - Change Attributes"
- Press "More Attributes" button
- Set "Plugin=jpeg-comment" "Property=EXIF_Photo_DateTimeOriginal" "Value=tc.Writedate"
- Press "More Attributes" button
- Set "Plugin=jpeg-comment" "Property=Exif_Photo_DateTimeDigitized" "Value=tc.Writedate"
- Press "More Attributes" button
- Set "Plugin=jpeg-comment" "Property=Exif_Image_DateTime" "Value=tc.Writedate"

(You may choose just one of them, but I do them all.)

Finally press OK button to start changing.

Just try it with a single file and if your result matches, you can save your settings from within the "Change Attributes" dialog ...

Thanks a lot for this efficient and quick answer.
In French version, it seems that tc->DateModif is the right parameter to use with Picasa.
I put exiv2 and its dll in windows\system2, the simplest place to find it

I had really no idea of where to look for that answer and, though being a very old user of TC (I already used NC on DOS !), I know very little on those possibilities, for instance the extension of Properties.
Is there a place to find this kind of information ? I didn't find that on ghisler's site, though everything is so nice.

Thanks again

You can check Clo's French TC manual for general information on content plugins and properties. Go to chapter 3.l -> Additifs -> 4. Modules de contenu.
