how to delete all EXIF tags except those from specified list

[vladak]

I'd like to delete all EXIF data from image but I'd like to preserve Orientation. I tried this:

  exiftool -exif:all= --exif:Orientation file.jpg

however it does not seem to be working - all exif tags are deleted including Orientation.

I am using exiftool 10.02 on OS X.

Try this:
exiftool -exif:all= -TagsFromFile @ -exif:Orientation file.jpg

Works fine, thanks a lot !
