NAME

       lensfun-add-adapter - add lens mount compatibilities to Lensfun's database

SYNOPSIS

       lensfun-add-adapter
       lensfun-add-adapter [--maker MAKER] [--model MODEL] [--mount MOUNT]
       lensfun-add-adapter --remove-local-mount-config

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 contains information about lens mounts of cameras and available mounts  for  lens  models.   This
       way,  the  calling application can offer the user a list with lenses that fit on their camera in order to
       pick one.  Otherwise, you would see all lenses every time.  This can be pretty overwhelming.

       But if you bought an adapter for another mount system, you would want to see lenses of that mount  system
       listed  for  your  camera.  So, you must tell Lensfun somehow that you own the adapter.  You can do so by
       calling lensfun-add-adapter.

       The easiest way to use it is to call it with no  parameters.   lensfun-add-adapter  will  then  enter  an
       interactive  mode.   First  you  have  to  enter your camera model.  lensfun-add-adapter will use that to
       determine the destination mount.  In particular, the extended lens lists will show up  for  every  camera
       with  that mount, not just the one you entered.  Then, you have to select the mount of the lenses you can
       now put on your camera, using the adapter.  That's it.

       With the options --maker, --model, and --mount, you can avoid interactive mode by passing the  nevcessary
       data  explicitly.  If you pass only maker/model or only mount, lensfun-add-adapter will enter interactive
       mode only for the missing data.

       You can also use lensfun-add-adapter to reset your  adapter  configuration.   Call  it  with  the  --help
       paremeter to see all functions.

OPTIONS

       --maker MAKER --model MODEL
              The  exact  maker  and model of the camera the mount of which should be made compatible.  You must
              provide these options only in combination rather than only one of them.

       --mount MOUNT
              The exact name of the mount of the lenses that should be made compatible.

       --remove-local-mount-config
              Resets the local mount configuration, i.e. the additional mount compatibilities that were  created
              by  this  program.  Effectively, it removes the file _mount.xml from the local Lensfun database of
              the current user.

FILES

       ~/.local/share/lensfun/_mounts.xml
              File with all mount compatibilities that were added by this program.
