Darktable is an open source photography workflow application and RAW developer. A virtual lighttable and darkroom for photographers. 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.
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).
The user interface is built around efficient caching of image metadata and mipmaps, all stored in a database. The main focus lies on user interaction, both in terms of a smooth interface design as well as processing speed. High quality output is also goal.
- Darktable runs on GNU/Linux/Gnome.
- Fully non-destructive editing.
- All darktable core functions operate on 4x32-bit floating point pixel buffers, enabling SSE instructions for speedups. It offers GPU acceleration via OpenCL (runtime detection and enabling) and has built-in ICC profile support: sRGB, Adobe RGB, XYZ and linear RGB.
- A collect plugin allows you to execute flexible database queries, search your images by tags, image rating (stars), color labels and many more. Filtering and sorting your collections within the base query or simple tagging by related tags are useful tools in your every-day photo workflow.
- Import a variety of standard, raw and high dynamic range image formats (e.g. jpg, cr2, hdr, pfm, .. ).
- darktable has a zero-latency fullscreen, zoomable user interface through multi-level software caches.
- Tethered shooting.
- darktable currently comes with 15 translations: albanian, catalan, czech, dutch, finnish, french, gaelic, german, italian, japanese, polish, russian, spanish, swedish and thai.
- The powerful export system supports picasa webalbum, flickr upload, disk storage, 1:1 copy, email attachments and can generate a simple html-based web gallery. darktable allows you to export to low dynamic range (jpg, png, tiff), 16-bit (ppm, tiff), or linear high dynamic range (pfm, exr) images.
- darktable uses both xmp sidecar files as well as its fast database for saving metadata and processing settings. All Exif data is read and written using libexiv2.
Changes in this release:GUI:
- darktable has been ported to gtk-3.0
- the viewport in darkroom mode is now dynamically sized, you specify the border width
- side panels now default to a width of 350px in dt 2.0 instead of 300px in dt 1.6
- further hidpi enhancements
- navigating lighttable with arrow keys and space/enter
- brush size/hardness/opacity have key accels
- allow adding tone- and basecurve nodes with ctrl-click
- the facebook login procedure is a little different now
- image information now supports gps altitude
- new print mode
- reworked screen color management (softproof, gamut check etc.)
- delete/trash feature
- pdf export
- export can upscale
- new "mode" parameter in the export panel to fine tune application of styles upon export
- new thumbnail cache replaces mipmap cache (much improved speed, stability and seamless support for even up to 4K/5K screens)
- all thumbnails are now properly fully color-managed
- it is now possible to generate thumbnails for all images in the library using new darktable-generate-cache tool
- we no longer drop history entries above the selected one when leaving darkroom mode or switching images
- high quality export now downsamples before watermark and framing to guarantee consistent results
- optimizations to loading jpeg's when using libjpeg-turbo with its custom features
- asynchronous camera and printer detection, prevents deadlocks in some cases
- noiseprofiles are in external JSON file now
- aspect ratios for crop&rotate can be added to config file
- color reconstruction module
- magic lantern-style deflicker was added to the exposure module (extremely useful for timelapses)
- text watermarks
- shadows&highlights: add option for white point adjustment
- more proper Kelvin temperature, fine-tuning preset interpolation in white balance iop
- monochrome raw demosaicing (for cameras with color filter array physically removed)
- raw black/white point module
- 32-bit support is soft-deprecated due to limited virtual address space
- support for building with gcc earlier than 4.8 is soft-deprecated
- numerous memory leaks were exterminated
- overall stability enhancements
