there is no plugin for that actually.
But you can use Exiv2 command line program to batch extract Exif tag and store
it to a file. With a script, it's not very complicated to do. Perhaps
somebody have alredy done something like that...
Note : actually, digiKam cannot process searchs about photo exif tag like Lens
focal, aperture, shutter speed, flash, GPS info, etc. but in the future, we
will implemente this feature.
In fact there is already a file in B.K.O about this subject. To implement this
feature, we need to add new array in the database to store these
informations. This will be done later 0.9.0 because we not would change the
database in 0.9.0 to preserve compatibility with 0.8.x serie, and limit
changes in source code for this release (there are too many changes in 0.9.0)
Also, there is another file in B.K.O to improve the DB interface in digiKam to
support others DB frontends than sqLite like mySQL for example. This will be
done at the same time, later 0.9.0, when digiKam will be ported to QT4.x
because database API in QT4.x is more simple than QT3.x
To resume, later 0.9.0, the first task to do is to port digiKam to QT4.x and
after working on DB stuff... We will certainly create a new developpemt
branch in svn for that : one to maintain 0.9.0, another one for QT4 port.
