DESCRIPTION
darktable is a digital photography workflow application for Linux and Mac OS X in the
lines of Adobe Lightroom and Apple Aperture.
The application is designed to ease editing and consistent processing of large photo
sessions and provides a easy to use digital light-table and a set of sophisticated post-
processing tools.
Most processing is done in 32-bit floating point per channel mode in device independent
CIE L*a*b* color space. darktable is also fully color managed, which gives you full
control over the look of the photos.
The application relies on a modern plug-in architecture thus making it easy for 3rd party
developers to extend the existing capabilities of the application. All light-table and
darkroom features are implemented as plug-ins, so you can create your plug-ins reusing
existing code.
COMMAND LINE ARGUMENTS
IMG_1234.RAW or image_folder/
You may optionally supply the filename of an image or the name of a folder containing
image files. If a filename is given darktable starts in darkroom view with that file
opened. If a folder is given darktable starts in lighttable view with the content of
that folder as the current collection.
-d <debugoption>
This option enables debug output to the terminal. There are several subsystems of
darktable and debugging of each of them can be activated separately. You can use this
option multiple times if you want debugging output of more than one subsystem.
A few of those debugoptions are:
control
Enable job queue debugging. If you redirect darktable's output to control.log and
call ./tools/create_control_svg.sh control.log, you will get a nice control.svg
with a visualization of the threads' work.
cache
This will give you a lot of debugging info about the mipmap cache for light table
mode. If compiled in debug mode, this will also tell you where in the code a
certain buffer has last been locked.
perf
Use this for performance tweaking your darkroom modules. It will rdtsc-measure the
runtimes of all plugins and print them to stdout.
all Enable all debugging output.
--disable-opencl
Prevent darktable from initializing the OpenCL subsystem. Use this option in case
darktable crashes at startup due to a defective OpenCL implementation.
--library <library file>
darktable keeps image information in an sqlite database for fast access. The default
location of that database file is "$HOME/.config/darktable/library.db". You may give
an alternative location, e.g. if you want to do some experiments without compromising
your original library.db. If the database file does not exist, darktable creates it
for you. You may also give ":memory:" as a library file in which case the database is
kept in system memory - all changes are discarded when darktable terminates.
--datadir <data directory>
This option defines the directory where darktable finds its runtime data. The default
place depends on your installation. Typical places are
"/opt/darktable/share/darktable/" and "/usr/share/darktable/".
--moduledir <module directory>
darktable has a modular structure and organizes its modules as shared libraries for
loading at runtime. With this option you tell darktable where to look for its shared
libraries. The default place depends on your installation; typical places are
"/opt/darktable/lib64/darktable/" and "/usr/lib64/darktable/".
--tmpdir <tmp directory>
The place where darktable stores its temporary files. If this option is not supplied
darktable uses the system default.
--configdir <config directory>
This option defines the directory where darktable stores the user specific
configuration. The default place is "$HOME/.config/darktable/".
--cachedir <cache directory>
darktable keeps a cache of image thumbnails for fast image preview and of precompiled
OpenCL binaries for fast startup. By default the cache is located in
"$HOME/.cache/darktable/". There may exist multiple thumbnail caches in parallel - one
for each library file.
--localedir <locale directory>
The place where darktable finds its language specific text strings. The default place
depends on your installation. Typical places are "/opt/darktable/share/locale/" and
"/usr/share/locale/".
--conf <key>=<value>
darktable supports a rich set of configuration parameters which the user defines in
"darktablerc" - darktable's configuration file in the user config directory. You may
temporarily overwrite individual settings on the command line with this option -
however, these settings will not be stored in "darktablerc".

HISTORY
The project was started by Johannes Hanika in early 2009 to fill the gap (or, rather, a
black hole) of a digital photography workflow tool on Linux.
