HI folks,
I'm using darkable 2.6.2 on Ubuntu Linux 19.04.
My lens (NIkon 200-500mm f/5.6 ER VR) does not appear in the lens
correction choices.
I downloaded the latest master branch of lensfun from github, compiled it
and installed it, apparently successfully.
The new version of lensfun does in fact have correction data for my lens.
It's been installed to /usr/local/share/lensfun/version_2/slr-nikon.xml.
Nevertheless, when I restart darktable, the lens choice list does not
include my lens.
Do I need to configure darktable to read the updated database?
Thanks!
BTW, the excerpt below from
/usr/local/share/lensfun/version_2/slr-nikon.xml contains the info for my
lens:
