Modules
Currently darktable carries sixty one photograph operation modules. Many modules support effective mixing operators supplying combination capability that works on the incoming photo records and the output of the contemporary module or be used with drawn mask.
Basic photograph operations:
Contrast, brightness, saturation: Quickly track your photograph the usage of this simple module.
Shadows and highlights: Improve photographs with the aid of lightening shadows and darkening highlights. Read Ulrich's blog submit on this.
Crop and rotate: This module is used to crop, rotate and correct the angle of your image. It also consists of many helpful suggestions that help you using the equipment (e.G. Rule of thirds or golden ratio).
Base curve: darktable comes with widespread more advantageous basecurve presets for several fashions that are robotically applied to raw images for better shades and comparison.
Exposure controls: Tweak the photo publicity both via the use of the sliders in the module or dragging the histogram around.
Demosaic: You have the choice between several demosaicing methods when modifying raw documents.
Highlight reconstruction: This module attempts to reconstruct shade information that is generally clipped because of facts now not being complete in all channels.
White stability: A module supplying 3 approaches to set the white stability. You can set tint and temperature otherwise you outline the price of every channel. The module gives predefined white stability settings as well. Or simply choose a neutral area within the photo to balance for that.
Invert: A module inverting hues based totally on the shade of movie material.
Tone photo operations:
Fill light: This module permits the nearby amendment of the publicity based totally on pixel lightness.
Levels: This module offers the well-known degrees adjustment equipment to set black, gray and white points.
Tone curve: This module is a classical device in digital pictures. You can change the lightness through dragging the road up or down. Darktable lets you one after the other manage the L, a and b channel. Read in Ulrich's weblog post how to make use of this selection.
Zone device: This module adjustments the lightness of your photograph. It is based on the Ansel Adams system. It lets in to adjust the lightness of a zone considering the impact on the adjoining zones. It divides the lightness in a person-described variety of zones.
Local comparison: This module can be used to boost details within the photo.
Two exceptional tone mapping modules: These modules allow to recreate some comparison for HDR pics.
Color photo operations:
Velvia: The velvia module complements the saturation within the photograph; it increases saturation on lower saturated pixels greater than on high saturated pixels.
Channel mixer: This module is a effective device to manage channels. As access, it manipulates red, green and blue channels. As output, it makes use of purple, green, blue or gray or hue, saturation, lightness.
Color assessment
Color correction: This module can be used to regulate the global saturation or to provide a tint. Read Johannes' weblog publish.
Monochrome: This module is a short manner to transform an photo to black and white. You can simulate a color filter out to be able to adjust your conversion. The filter out may be modified in size and shade center.
Color zones: This module permits to selectively alter the colors in your photograph. It is rather flexible and permits each transformation viable in the LCh colorspace.
Color balance: Use lift/gamma/advantage to trade highlights, midtones and shadows.
Vibrance: For a detailed description study Henrik's blog post.
Color look up table: Apply patterns or film emulations. You can also effortlessly edit the modifications done. For more facts you can examine this blog submit
Input/output/display coloration profile control
A useful function that shows pixels outside the dynamic range.
Correction modules:
Dithering: This helps with banding in clean gradients inside the very last photo.
Sharpen: This is a popular UnSharp Mask tool for sharpening the information of an picture.
Equalizer: This flexible module may be used to attain a number of consequences, such as bloom, denoising, and neighborhood evaluation enhancement. It works within the wavelet area, and parameters may be tuned for each frequency band separately.
Denoise (non-neighborhood means): Denoising with separated colour / brightness smoothing.
Defringe: Remove coloration fringes on high contrast edges.
Haze elimination: This module lets in to cast off the low evaluation and coloration tint coming from haze and air pollutants.
Denoise (bilateral filter): Another denoising module.
Liquify: Push photo parts around, grow them, reduce them. More facts can be found on this weblog publish
Perspective correction: A wonderful module to robotically un-distort pictures with immediately strains. See our blog put up for an advent and examples.
Lens correction: lens disorder correction the use of lensfun.
Spot elimination: Spot removal permits you to accurate a zone in your photo by the use of any other zone as version.
Profiled denoise: By measuring the everyday noise of cameras on the unique ISO levels darktable is able to take away a variety of it. Read this blog post for extra data.
Raw denoise: Raw denoise lets in you to perfom denoising on pre-demosaic data. It is ported from dcraw.
Hot pixels: This module permits you to visualise and correct stuck and hot pixels.
Chromatic aberrations: This module routinely detects and corrects chromatic aberrations.
Effects/creative photograph postprocessing:
Watermark: The watermark module presents a way to render a vector-based overlay onto your picture. Watermarks are fashionable SVG files and can be designed the use of Inkscape. The SVG processor of darktable additionally substitutes strings inside the SVG document which offers the opportunity to consist of picture-based records within the watermark such as aperture, publicity time and different metadata.
Framing: This module allows you to add an artistic body round an image.
Split firming: Original split firming approach creates a coloration linear toning effect where the shadows and highlights are represented by way of two exceptional colors. Darktable split toning module is more complex and offers extra parameters to tweak the result.
Vignetting: This module is an artistic characteristic which creates vignetting (modification of the brightness/saturation at the borders).
Soften: This module is a creative function that creates the Orton effect additionally usually called softening the photo. Michael Orton achieved such result on slide film by using the usage of 2 exposures of the equal scene: one nicely uncovered and one overexposed; then he used a way to mixture those into a very last photograph in which the overexposed picture became blurred.
Grain: This module is a creative characteristic which simulates the grain of a movie.
Highpass: This module acts as highpass filter.
Lowpass: This module acts as lowpass clear out. One use case is defined in Ulrich's blog put up.
Lowlight imaginative and prescient: Low mild module lets in to simulate human lowlight imaginative and prescient, as a consequence supplying the capability to make lowlight pictures look in the direction of reality. It also can be used to carry out a day to night time conversion.
Bloom: This module boost highlights and softly blooms them over the image.
Color mapping: Transfer colors from one photo to another.
Colorize
Graduated density: This module objectives at simulating a neutral density filter, a good way to accurate exposure and color in a revolutionary way.
What's New
Editing history is now periodically vehicle-saved (each 10 seconds) even as modifying snap shots in the darkroom view. The auto-save c program languageperiod can be modified (through a preference) or vehicle-keep can be disabled totally (with the aid of placing the c language to 0).
A new processing module rgb primaries has been delivered. This module may be used for sensitive coloration corrections as well as innovative color grading. It permits the red, inexperienced and blue primary colorings to be moved round the usage of "hue" and "purity" controls.
The underlying pixel operation is largely the same as channel mixing.
In addition, the sigmoid module now consists of a brand new primaries section, which can be used to gracefully handle hard lighting fixtures conditions (e.G. LEDs) and tune the overall appearance of the image. Modifying these
parameters can offer alluring sunsets, advanced pores and skin tones and so forth.
This characteristic can best be used with sigmoid's according to-channel mode and is loosely primarily based on ideas from Troy Sobotka's AgX and related paintings in the Blender network.
The blanketed "smooth" preset should offer a good start line for further corrections the use of this selection.
When operating with the liquify and retouch modules, the overall uncropped photo is now continually shown, with any crop indicated via displaying an overlaid rectangle. This permits for cropped-out parts of the photo for use while not having to first disable the crop module and re-allow it when completed.
When panning or zooming inside the darkroom view, a low resolution placeholder was once proven till the picture become absolutely recalculated for the newly-visible vicinity. Now, if any part of the previous view is still seen, that component can be at once proven in high high-quality, with handiest the remainder of the photograph
being briefly shown in low satisfactory till the pipe has finished.
This has been carried out as a part of a complete remodeling of the darkroom photo display, which has also eliminated some annoying jumps when changing the low decision placeholder with recalculated photo information, or while switching among complete and cropped view (when the crop, retouch or liquify modules are (un)focused).
Performance Improvements
OpenCL is now initialized inside the heritage immediately after launching the darktable UI, with development indicated by way of a sequence of toast messages. Previously, this changed into executed before the primary UI changed into launched, that could lead to extensive delays (occasionally more than a minute) between the user starting darktable and whatever performing on-display screen, making it appear as even though darktable had didn't begin. Note that processing can be slower (given that darktable will simplest use the CPU) till OpenCL is absolutely initialized.
An OpenCL code path has been implemented for lens correction the use of embedded correction metadata.
Image display speed in the map view has been multiplied by using 25%.
Export velocity has been progressed for JPEG 2000 and B&W TIFF photographs.
The chromatic aberrations module is now about 10% quicker whilst run at the CPU.
