Another way to approach such problems if one can do unix shell
scripting is to use the GEGL binary directly.

$ ls
IMG_1883.JPG  IMG_1885.JPG  IMG_1887.JPG
$ mkdir output
$ for input in *.JPG; do echo $input;gegl $input -o output/$input  --
lens-distortion main=-23 zoom=1.2 ; done
# make and drink tea

Note that GEGL loads/quries all its plugins on startup; slowing the
this type of batch processing down since a new GEGL instance is
created for each image.
