Darktable manages your digital negatives in a database and lets you view them through a zoomable lighttable. it also enables you to develop raw images and enhance them. It tries to fill the gap between the many excellent existing free raw converters and image management tools (such as ufraw or f-spot). The user interface is built around efficient caching of image metadata and mipmaps, all stored in a database. the user will always be able to interact, even if the full resolution image is not yet loaded.
