Removing tags from Makernotes

[BogdanH]

Hi Phil,

I'm just curious: how come, one can remove i.e. -SerialNumber tag from NEF Makernotes, but not from CR2?


My mistake... tag actually isn't removed from NEF, it's content is just set to "empty" by using:
exiftool -SerialNumber= MyPhoto.NEF
The same command for CR2 doesn't change anything.

Hi Bogdan,

You can't delete either.  Since the Nikon serial number is stored as a string, the -serialnumber= syntax works to set the serial number to an empty string.

However, Canon stores the serial number as an integer, so with CR2 images the closest equivalent would be -serialnumber=0
