Missing info from exif.Canon tags

Lars Gullik Bjønnes

There are quite a few more known exif.Canon tags than what digikam
shows.

http://search.cpan.org/src/EXIFTOOL/Image-ExifTool-6.76/html/TagNames/Canon.html

Of these 0x0095 LensType is one of the more useful. Esp. since this is
a tag it would be great to search for among all the pictures.
(as would searching for specific aparature, speed, focal length)
       

(Sorry for sending this to the digikam list... but the interface for
communicationg with exiv2 project is just too cumbersome...)

These informations are decoded by Exiv2 library not digiKam itself.
 
For Exiv2 0.13, i have backported a lot of makernote from ExifTool database. Please update and try again.
 
If it's not enough, please use Exiv2 bugzilla, not digiKam...

There does not seem to be any Canon tag fixes there.  I just had a
look at src/canonmn.cpp and it seems to miss quite a lot of the info
found in the link I provided.

That would mean getting (even yet) another account that I do not want
of need.

If I could find a direct mail address for the exiv2 develoment
mailinglist I would use that. (Or is a forum the only thing that exist?)

Hi Lars,

There is an Exiv2 forum and the bug tracker.
With the username from http://www.exiv2.org/support.html you can post to
the forum without the need for an account. In order to report bugs you
need an account. There is no separate devel forum or group.

It would be great if you could provide a patch for the tags and values
that you are missing. For the majority of cases, adding them is quite
straightforward. You can send the patch to the forum or to me directly.

Thanks,
Andreas
