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.
General Info:
- 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:
New Features:- Filter-out some EXIF tags when exporting. Helps keep metadata size below max limit of ~64Kb
- Support the new Canon EOS 80D {m,s}RAW format
- Always show rendering intent selector in lighttable view
- Clear elevation when clearing geo data in map view
- Temperature module, invert module: add SSE vectorization for X-Trans
- Temperature module: add keyboard shortcuts for presets
- JPEG format writer: use libexiv2 to write metadata, like with other formats
- Accept non-mosaiced raw files with 4 channels, assume they are RGBA (alpha channel is ignored)
- Rawspeed: fixes for building with libjpeg (as opposed to libjpeg-turbo)
- OpenCL: always use blocking memory transfer hostdevice
- OpenCL: remove bogus static keyword in extended.cl
- Fix crash with missing configured display profile
- Histogram: always show aperture with one digit after dot
- Show if OpenEXR is supported in --version
- Rawspeed: use a non-deprecated way of getting OSX version
- Don't show bogus message about local copy when trying to delete physically deleted image
- OpenCL: properly discard CPU-based OpenCL devices. Fixes crashes on startup with some broken OpenCL implementations like pocl.
- darktable-cli: do not even try to open display, we don't need it.
- Rawspeed: NikonDecoder: stop accepting generic camera entries. Fixes multitude of Nikon raw loading issues.
- OpenCL: fix border handling in crop&rotate module
- Hotpixels iop: make it actually work for X-Trans
- Clipping IOP: scale width of gray crop path with zoom level
- One more fixup to canon lens name reading from exif
- Fixup Bayer pattern for Olympus SP570UZ
