How do I write a composite tag?

[jaap.verhage]

Hello everybody,

in the list "Canon tags" at http://www.exiftool.org/TagNames/Canon.html#LensType , mention is made in the part "Canon LensType Values" of "composite tags", like some LensID tags. They take the form of, for example, "45.1". My question is: how do I write such a composite tag into a Canon RAW image file? Just executing exiftool.exe LensID=45.1 image.cr2 in a Windows CMD window won't work.

Thanks for your help.

Regards, Jaap.

Hi Jaap,

how do I write such a composite tag into a Canon RAW image file?

This question is answered by the 3rd sentence in the Composite tags documentation.  However, the LensID tag is particularly complex because there are various versions derived from different tags depending on the camera make.  And there are lots of tags involved.  So changing the LensID may take some work.

Oh dear, I was afraid of this... sorry for taking up your time, but thanks for answering so promptly. I'll look into the documentation and come back to you if I'm too stupid to understand it  .
