Is it possible to create a new user lensfun file where such corrections can be made, so as to avoid editing the official lensfun DB files? e.g. if the lensfun DB is in
/usr/share/lensfun/version_1/
can a user create
~/RTstuff/compact-panasonic.xml
with the required corrections? Or would a generic
~/RTstuff/my_lensfun.xml
be possible?
And how should RT find it?
I ask because it’s not a good idea to ask users to edit system lensfun DB files, at least not in Linux.
