[$] Raw photo development with darktable

One of your editor's long-time hobbies is photography; it is an activity
that can be rewarding even with the lack of any particular talent — a useful
attribute. Photography has changed greatly over the years; as a result,
those hard-earned darkroom skills are of little use, and photo processing
has become yet another software problem. This is a field that supports a
lot of proprietary software, but there is also no shortage of free software
available. The time has come to combine work and pleasure and catch up
with the state of free software for photography, starting with the darktable raw photo editor.
