Darktable 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.
- Non-destructive editing throughout the complete workflow, your original images are never modified.
- Take advantage of the real power of raw: All darktable core functions operate on 4x32-bit floating point pixel buffers, enabling SSE instructions for speedups.
- GPU accelerated image processing: many image opertions are lightning fast thanks to OpenCL support (runtime detection and enabling).
- Professional color management: darktable is fully color managed, supporting automatic display profile detection on most systems, including built-in ICC profile support for sRGB, Adobe RGB, XYZ and linear RGB color spaces.
- Cross platform: darktable runs on Linux, macOS / macports, BSD, Windows and Solaris 11 / GNOME.
- Filtering and sorting: search your image collections by tags, image rating (stars), color labels and many more, use flexible database queries on all metadata of your images.
- Image formats: darktable can import a variety of standard, raw and high dynamic range image formats (e.g. JPEG, CR2, NEF, HDR, PFM, RAF ... ).
- Zero-latency, zoomable user interface: through multi-level software caches darktable provides a fluid experience.
- Tethered shooting: support for instrumentation of your camera with live view for some camera brands.
- Speaks your language: darktable currently comes with 21 translations: Albanian, Catalan, Czech, Danish, Dutch, French, German, Greek, Hebrew, Hungarian, Italian, Japanese, Polish, Portuguese (Brazilian and Portuguese), Russian, Slovak, Slovenian, Spanish, Swedish, Ukrainian.
- Powerful export system supports G+ and Facebook webalbums, 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 (JPEG, PNG, TIFF), 16-bit (PPM, TIFF), or linear high dynamic range (PFM, EXR) images.
- Never lose your image development settings 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.
- Automate repetitive tasks: Many aspects of darktable can be scripted in Lua.
Currently darktable contains 61 image operation modules. Many modules support powerful blending operators offering blend functionality that works on the incoming image information and the output of the current module or be used with drawn masks.
Basic image operations:
- Contrast, brightness, saturation: Quickly tune your image using this simple module.
- Shadows and highlights: Improve images by lightening shadows and darkening highlights. Read Ulrich's blog post on this.
- Crop and rotate: This module is used to crop, rotate and correct the perspective of your image. It also includes many helpful guidelines that assist you using the tools (e.g. rule of thirds or golden ratio).
- Base curve: darktable comes with general enhanced basecurve presets for several models that are automatically applied to raw images for better colors and contrast.
- Exposure controls: Tweak the image exposure either by using the sliders in the module or dragging the histogram around.
- Demosaic: You have the choice between several demosaicing methods when editing raw files.
- Highlight reconstruction: This module tries to reconstruct color information that is usually clipped due to information not being complete in all channels.
- White balance: A module offering three ways to set the white balance. You can set tint and temperature or you define the value of each channel. The module offers predefined white balance settings as well. Or just pick a neutral region in the image to balance for that.
- Invert: A module inverting colors based on the color of film material.
Tone image operations:
- Fill light: This module allows the local modification of the exposure based on pixel lightness.
- Levels: This module offers the well-known levels adjustment tools to set black, grey and white points.
- Tone curve: This module is a classical tool in digital photography. You can change the lightness by dragging the line up or down. darktable lets you separately control the L, a and b channel. Read in Ulrich's blog post how to make use of this feature.
- Zone system: This module changes the lightness of your image. It is based on the Ansel Adams system. It allows to modify the lightness of a zone taking into account the effect on the adjacent zones. It divides the lightness in a user-defined number of zones.
- Local contrast: This module can be used to boost details in the image.
- Two different tone mapping modules: These modules allow to recreate some contrast for HDR images.
Color image operations:
- Velvia: The velvia module enhances the saturation in the image; it increases saturation on lower saturated pixels more than on high saturated pixels.
- Channel mixer: This module is a powerful tool to manage channels. As entry, it manipulates red, green and blue channels. As output, it uses red, green, blue or grey or hue, saturation, lightness.
- Color contrast
- Color correction: This module can be used to modify the global saturation or to give a tint. Read Johannes' blog post.
- Monochrome: This module is a quick way to convert an image to black and white. You can simulate a color filter in order to modify your conversion. The filter can be changed in size and color center.
- Color zones: This module allows to selectively modify the colors in your image. It is highly versatile and allows every transformation possible in the LCh colorspace.
- Color balance: Use lift/gamma/gain to change highlights, midtones and shadows.
- Vibrance: For a detailed description read Henrik's blog post.
- Color look up table: Apply styles or film emulations. You can also easily edit the changes done. For more information you can read this blog post
- Input/output/display color profile management
- A useful feature that displays pixels outside the dynamic range.
- Dithering: This helps with banding in smooth gradients in the final image.
- Sharpen: This is a standard UnSharp Mask tool for sharpening the details of an image.
- Equalizer: This versatile module can be used to achieve a variety of effects, such as bloom, denoising, and local contrast enhancement. It works in the wavelet domain, and parameters can be tuned for each frequency band separately.
- Denoise (non-local means): Denoising with separated color / brightness smoothing.
- Defringe: Remove color fringes on high contrast edges.
- Haze removal: This module allows to remove the low contrast and color tint coming from haze and air pollution.
- Denoise (bilateral filter): Another denoising module.
- Liquify: Push image parts around, grow them, shrink them. More information can be found in this blog post
- Perspective correction: A great module to automatically un-distort shots with straight lines. See our blog post for an introduction and examples.
- Lens correction: lens defect correction using lensfun.
- Spot removal: Spot removal allows you to correct a zone in your image by using another zone as model.
- Profiled denoise: By measuring the typical noise of cameras at the different ISO levels darktable is able to remove a lot of it. Read this blog post for more information.
- Raw denoise: Raw denoise allows you to perfom denoising on pre-demosaic data. It is ported from dcraw.
- Hot pixels: This module allows you to visualize and correct stuck and hot pixels.
- Chromatic aberrations: This module automatically detects and corrects chromatic aberrations.
Effects/artistic image postprocessing:
- Watermark: The watermark module provides a way to render a vector-based overlay onto your image. Watermarks are standard SVG documents and can be designed using Inkscape. The SVG processor of darktable also substitutes strings within the SVG document which gives the opportunity to include image-dependent information in the watermark such as aperture, exposure time and other metadata.
- Framing: This module allows you to add an artistic frame around an image.
- Split toning: Original split toning method creates a two color linear toning effect where the shadows and highlights are represented by two different colors. darktable split toning module is more complex and offers more parameters to tweak the result.
- Vignetting: This module is an artistic feature which creates vignetting (modification of the brightness/saturation at the borders).
- Soften: This module is an artistic feature that creates the Orton effect also commonly known as softening the image. Michael Orton achieved such result on slide film by using 2 exposures of the same scene: one well exposed and one overexposed; then he used a technique to blend those into a final image where the overexposed image was blurred.
- Grain: This module is an artistic feature which simulates the grain of a film.
- Highpass: This module acts as highpass filter.
- Lowpass: This module acts as lowpass filter. One use case is described in Ulrich's blog post.
- Lowlight vision: Low light module allows to simulate human lowlight vision, thus providing the ability to make lowlight pictures look closer to reality. It can also be used to perform a day to night conversion.
- Bloom: This module boost highlights and softly blooms them over the image.
- Color mapping: Transfer colors from one image to another.
- Graduated density: This module aims at simulating a neutral density filter, in order to correct exposure and color in a progressive manner.
The following is a summary of the main features added to darktable 4.2. Most of these features are described more fully in the user manual.
- New Sigmoid display transform module, which can be used in place of the filmic and base curve modules.
- Two new algorithms are provided in the highlight reconstruction module: "inpaint opposed" and "segmentation based". The "inpaint opposed" algorithm has proved to be very stable and provides good results in many images, so it replaces "clip highlights" as the new default algorithm.
- The pixelpipe used for image display in the darkroom view has been reworked so that it can be used elsewhere (darkroom view, second display window, duplicate manager, style preview, snapshot routine). This has allowed for code de-duplication as well as enhancement of many of these features (see below).
- The second darkroom image window has now been enhanced to support both the focus peaking and ISO-12646 color assessment modes.
- The snapshot module has been entirely reworked so that, instead of using a fixed screen capture it now uses a dynamically generated view using the new pixelpipe functionality. This means that it can now be zoomed and panned with keyboard/mouse.
- The duplicate manager previously used a different pipe routine to calculate its previews (i.e. when long-pressing on a duplicate image thumbnail) which often meant that the displayed duplicates differed from the main darkroom view in subtle ways. Use of the new pipe routine now means that these previews will be identical to those produced during darkroom editing.
- It is now possible to preview the effect of a user-generated style on an image before applying it. Simply hover over the style name in either the lighttable styles module or the darkroom quick-access menu and a new tooltip will appear, showing the image with the style applied along with details of the modules that are included.
- Some cameras record lens correction information within the image EXIF metadata. The lens correction module has been enhanced so that it can extract this data and use it to correct lens distortions.
- darktable is now able to read and write JPEG XL images
- Processing and utility modules have been altered so that if a module is not entirely visible when expanded, it will be automatically scrolled until the entire UI is visible on screen.
- For users who currently use the "scroll to the top when expanded" preference setting to achieve this effect, this change may provide a better alternative.
- As part of this change, a new animation effect has been added when expanding/collapsing modules. The speed of the expand/collapse animation can be controlled via a preference setting (preferences > miscellaneous > duration of ui transitions). Set this to zero to disable the animation.
- The pixelpipe caching functionality has been completely overhauled. More cachelines are used with an improved hit-rate while controlling the total amount of memory used, leading to a significantly faster interface.
- The slideshow has been rewritten for a better user experience. A small preview is displayed while the full image is computed to provide feedback to the user that something is being done in the background.
- A new drop-down menu has been added to the top filter bar to allow filters to be easily added and removed. Some range widgets have been removed from this list as they are not easily readable on the top bar.
- The UI of the range rating filter widget has been reworked for better readability. This revised widget is designed to be easier to use and more efficient.
