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
