NAME

       lensfun-update-data - update Lensfun's database

SYNOPSIS

       lensfun-update-data

DESCRIPTION

       Lensfun  is  a  library that corrects flaws in photographic images introduced by the lens.
       It also contains a comprehensive database  of  cameras  and  lenses  together  with  their
       characteristics  to  be  able  to  apply  automatic corrections of images taken with these
       devices.  Lensfun is used  by  darktable,  digiKam,  rawstudio,  GimpLensfun,  UFRaw,  and
       others.

       lensfun-update-data  is  a command-line program that updates Lensfun's database.  It looks
       whether a new version is available online, and if this is the case, it fetches the  latest
       version  and  installs  it  locally.   If  called  as  root,  the  database  is  installed
       system-wide, otherwise, it is installed in the user's directory.

FILES

       lensfun-update-data will place  the  fetched  database  in  /var/lib/lensfun-updates/  (if
       called  as root) or in ~/.local/share/lensfun/updates/ (otherwise).  If necessary, it will
       create this directory.  If there is already a database, it is replaced fully.  If  Lensfun
       detects  a  database  in one of these directories, it will use that instead of the default
       location below /usr/....

DIAGNOSTICS

       lensfun-update-data prints log messages to stdout.

       Exit status:
