Free Software Projects
A selection of Free/Libre Open Source Software projects related to photography.
For a newcomer (and some seasoned users) the number of different imaging projects can be a little overwhelming.
The primary projects you will probably consider for general purpose photography will likely be a raw processor and possibly pixel editing.
Commercial programs are mentioned here only as a point of reference for newcomers. None of these projects aspire to be like (or really care about) the commercial offerings.
A solid option for raw processing, library management, and reasonable replacement for the commercial Lightroom, would be either darktable or RawTherapee.
For pixel-editing and similar functionality to what you might find in Photoshop, GIMP is an awesome option (even awesomer when extended with the G’MIC plugin).
