How to read maker notes

Sorry, maybe I do something wrong, when I try to read the maker notes. Can you give me an example please? Be sure, I read the manpage more than once.

The maker notes are extracted automatically.  Use "exiftool -G" if you want to see what tags came from the MakerNotes.

Thanks, -G ...  | grep MakerNotes does the job, but I assume that a lot of MakerNotes are not displayed with a Caplio R1

I only see this:

[MakerNotes]    Maker Note Type                 : Rdc

[MakerNotes]    Maker Note Version              : Rev0106

[MakerNotes]    Ricoh Date Time 1               : 2004:10:29

[MakerNotes]    Ricoh Date Time 2               : 2004:08:05

Use "-U" to see the unknown information, and "-a" to display duplicate information.  Much of the Caplio RR1 information is still unknown.  Do you own one of these cameras?  If so, it would be very useful to me if you could figure out the meanings for some of this unknown information:

Code:

I own a Caplio R1 (http://www.ricoh.com/r_dc/caplio/r1/), not a RR1.

What can I do for you? I have no idea of the meanings of the tags above.

The steps to decoding new information are to systematically change camera settings and look for corresponding changes in the maker notes information.  You have to use your investigative powers to discover the meaning of unknown information.

I suggest you email me directly rather than posting to this forum and we can discuss this in more detail.  My email address is in the README file
