darktable [Графика и фото]
Organize and develop images from digital cameras
darktable manages your digital negatives in a database and lets you view them through a lighttable.
It also enables you to develop raw images and enhance them in a darkroom.
Other modes besides lighttable and darkroom are a map for geotagging, tethering, print and a slideshow.
darktable supports most modern cameras' raw formats, and does all of its processing at very high precision.
