Full implementation of color management.

Work in 32-bit float mode on a color channel in CIE LAB space.

Non-destructive editing with the XMP change description entry.

The program features built-in ICC profiles, GPU acceleration (based on OpenCL), and supports most common image formats. Rather than being immediately applied to raster data of the image, the program keeps the original image data until final rendering at the exporting stage - while parameter adjustments made by a user display in real-time. The core operates completely on floating point values, so darktable can not only be used for photography but also for scientifically acquired images or output of renderers (high dynamic range).Darktable involves the concept of non-destructive editing, similar to that of some other raw manipulation software.

Raw image loading is done using rawspeed, high-dynamic range and standard image formats such as jpeg are also supported. The full image is only converted during export. High quality output is also one of our goals.Īll editing is fully non-destructive and only operates on cached image buffers for display.

The main focus lies on user interaction, both in terms of a smooth interface design as well as processing speed. The user interface is built around efficient caching of image metadata and mipmaps, all stored in a database. The internal architecture of darktable allows users to easily add modules for all sorts of image processing, from the very simple (crop, exposure, spot removal) to the most advanced (simulation of human night vision). It’s also one of the very few FOSS projects able to do tethered shooting. It focuses on the workflow to make it easier for the photographer to quickly handle the thousands of images a day of shooting can produce. ufraw, rawstudio, f-spot, digikam, shotwell).

There are multiple alternatives in the open source world for raw development (ufraw, dcraw, rawtherapee) but darktable tries to fill the gap between the excellent existing free raw converters and image management tools (such as e.g. Raw is the unprocessed capture straight from the camera’s sensor to the memory card, nothing has been altered. It manages your digital negatives in a database, lets you view them through a zoomable lighttable and enables you to develop raw images and enhance them. A virtual lighttable and darkroom for photographers. Darktable is an open source photography workflow application and raw developer.
