Darktable is an free and open source photography workflow software and raw developer. It brings a virtual light-table and darkroom directly to your computer so that you can easily manage them.
Using Darktable, you can manage your photo negatives in digital form in a database within the comfort of your PC.
You can view the imported photos through a zoomable lighttable. It will fetch you details of the negative such as lens, exposure, aperture, focal length, focus distance, ISO, model, maker, film-roll, image id, filename, version, full path, width, height, copyright, local copy, date, time, title, creator, latitude, and longitude. From the light-table you are ready to develop raw images!
It supports importing a wide range of standard, RAW and HRD image formats including the most popular JPG, CR2, HDR, and PFM.
If you have been looking for a free alternative to Adobe Photoshop Lightroom, then Darktable is the one for you!
