Darktable

            
            Virtual lighttable and darkroom for photographers

Darktable manages your digital negatives in a database and lets you viewthem  through a zoomable lighttable. it also enables you to develop rawimages and enhance them.

It tries to fill the gap between the many excellent existing freeraw converters and image management tools (such as ufraw or f-spot).The user interface is built around efficient caching of image metadata andmipmaps, all stored in a database. the user will always be able to interact,even if the full resolution image is not yet loaded.

All editing is fully non-destructive and only operates on cached imagebuffers for display. the full image is only converted during export. Thefrontend is written in gtk+/cairo, the database uses sqlite3, raw imageloading is done using rawspeed, high-dynamic range, and standard image formatssuch as jpeg are also supported. The core operates completely on floatingpoint values, so darktable can not only be used for photography but also forscientifically acquired images or output of renderers (high dynamic range).
