There are multiple alternatives in the open source world for RAW development (ufraw, dcraw, rawtherapee) but darktable tries to fill the gap between the excellent existing free raw converters and image management tools (such as e.g. ufraw, rawstudio, f-spot, digikam, shotwell).

It's also one of the very few FOSS projects able to do tethered shooting.
