Hi Phil,
Assume, I have total empty (no metadata) jpg file. Then I add Exif:UserComment tag only. After doing that, exiftool automatically add some other exif tags (resolution, etc.) -that's not a problem.
The problem is, if I would like to keep those automatically added tags. The problem is, if I then delete UserComment only, all previously added tags are deleted too -except I assign some other (than default) values to them.
Is that normal/expected behaviour?
Greetings,
Bogdan

This is by design. I thought it made sense that if you add a tag then
remove it again you end up with the file you started with. So if you
delete a tag and only mandatory tags with the default values remain,
then they are deleted too.
If you want to keep the other mandatory tags, you could do something
like "-exifversion=0220" when you delete the UserComment tag.

Thank you for answering. It is really no big deal -I just want to be sure :-)
