I'm currently scanning a lot of old slides. The scanner I use has this annoying habit of adding "My beautiul picture" in a description field in the EXIF format.
I'd like to use an EXIF editor to get rid of that stupid message on each file, and add actually useful data, like the date I actually shot those pictures. Ideally, this should be able to work in batch mode (I have hundreds of those files).
What do you use?
