darktable is an open source photography workflow application and raw developer. A virtual lighttable and darkroom for photographers. It manages your digital negatives in a database, lets you view them through a zoomable lighttable and enables you to develop raw images and enhance them.
This is not an official darktable forum. While there are some occasional darktable devs lurking around, this forum is more for categorization here on pixls. (This doesn’t mean folks won’t still try to help and answer questions!)
The official means of communicating with the darktable team is either through the development mailing list or their users mailing list. Don’t forget that they are also reachable on their IRC channel at irc.freenode.net, channel #darktable. (Same server our IRC channel is located, on #pixls.us).
