A new Ratio-Corrected Demosaicing (RCD) algorithm has been added to the demosaic module. This will not provide forensic-level censorship.įor photographers using digital cameras with Bayer array sensors, which is most image sensors, new demosaic algorithms have been added. If you ever need to blur or pixelate selected parts of an image, such as to protect privacy or make an image suitable for certain social media platforms, a new 'censorize' module allows users to apply Gaussian blur and Gaussian noise to images selectively. We do not plan to let users add their own charts, and only reference charts from reputable manufacturers will be added to the library in the future.'
Regarding color checker support, darktable writes, 'X-Rite/Gretag Macbeth Passport 24 (pre-2014 and post-2014) and Spyder ColorChecker 24 and 48 (pre-2018 and post-2018) are currently supported. darktable 3.6 includes a new interface in its color calibration module to quickly extract the best white balance and RGB mixer settings from a color checker image. Color checkers, like a Datacolor X-Rite Passport, for example, are common tools in the industry. The new color balance module in darktable 3.6Īnother aspect of color editing that's changed in the new version of darktable is color checker support. Both saturation and chroma settings can be tuned globally and separately for shadows, midtones and highlights, using the luminance masks.'
While desaturating (in real saturation) also brightens and allows you to reach pastel colors (red degrades to pink), chroma reduction takes place at constant lightness and allows you only to reach a shade of gray with the same luminance (red degrades to gray), which is quite unpleasant and inconsistent with painting.
RECOVERING HIGHLIGHTS USING DARKTABLE SOFTWARE
It is important to note that, what 99% of software calls "saturation" is actually a setting that alters chroma (colorfulness irrespective of lightness). The color balance RGB module also includes what darktable calls real 'saturation.' This setting 'honors the Munsell and CIE (International Commission on Illumination) definition of saturation: colorfulness relative to lightness. It also uses luminance masks to split the image into shadows, highlights and midtones, allowing each to be color-graded separately. The module prevents users from pushing colors outside of the valid working range when editing. The color balance RGB module introduces several innovations to improve color editing. It uses a rational polynomial, similar to the Michaelis-Menten equation, 'which prevents the under- and over-shooting that can sometimes occur with high contrast and latitude when using the 'hard' and 'soft' interpolation methods.' The legacy workflow can still be manually enabled in the preferences.' Alongside the new image processing, there's a new interpolation method, dubbed 'safe.' It's the new default to build the characteristic 'S' shaped tone curve. The new 'quick access panel' replaces the old basic adjustments panel in darktable 3.6.ĭarktable writes, 'Now that scene-referred image processing is virtually feature-complete in darktable 3.6, scene-referred is now the default workflow.
A further improvement is the ability to add and remove modules from a module group quickly. Users can add controls from any module to the quick access panel, promising improved usability. The quick access panel includes a new interface that combines existing processing modules into a unified layout. First up is the new ' quick access panel,' a replacement for the old basic adjustments module and more. Version 3.6 adds numerous new features to darktable.
Darktable hopes to release a pair of major updates each year.īack to today's update.
RECOVERING HIGHLIGHTS USING DARKTABLE UPDATE
The latest update is the first of two planned feature releases, with the second intended to come out this winter. The darktable team has announced its second summer feature release, bringing darktable to version 3.6.
