![]() ![]() ![]() 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. It is important to note that, what 99% of software calls “saturation” is actually a setting that alters chroma (colorfulness irrespective of lightness). Third, the module introduces a real “saturation” setting that honors the Munsell and CIE (International Commission on Illumination) definition of saturation: colorfulness relative to lightness. The luminance masks are user-defined and viewable to allow complete and transparent control over the regions where the grading settings apply. The internal color algorithm is the usual slope/offset/power where the slope has been decomposed into two parts – a shadows lift and a highlights gain – each applied separately on different luminance masks. The classic slope/offset/power settings mostly affect highlights, shadows, and midtones implicitly, as an algorithmic side effect. Second, it uses luminance masks that explicitly split the image into real shadows, highlights and midtones, so that each can be color-graded separately. This makes daring color editing a lot safer and enables the creation of rich colors that won’t degrade into artifacts later. This ensures that color-grading does not push colors outside of the valid range, which could happen quickly when increasing saturation (as in the former color balance module). The color balance RGB module brings several unique innovations to help colorists edit pictures in a cinematographic way and with a refined level of control in a scene-referred and HDR-ready workflow.įirst, it sanitizes the color gamut in the RGB working space at the output of the module and internally between each color space conversion. The trade-off is that this method gives muted contrast near white and black (unless the latitude is increased), but allows much more drastic settings on the user-side without nasty side effects on the curve. This method uses a rational polynomial (similar to the Michaelis-Menten equation) which prevents the under- and over-shooting that sometimes occurs with high contrast and latitude when using the “hard” and “soft” interpolation methods. New spline in Filmic RGBĪ new interpolation method, dubbed safe, is the new default to build the characteristic “S” shaped tone curve. The legacy workflow can still be manually enabled in the preferences. Now that scene-referred image processing is virtually feature-complete in darktable 3.6, scene-referred is now the default workflow. You can also now auto-apply module group presets depending on the type of image you are editing. The manage module layouts window has also been enhanced to include setup for the quick access panel. You can also quickly access the manage module layouts window by Ctrl+clicking on the preset menu icon. This avoids the need to modify the group in the maintenance window, but bear in mind that it doesn’t yet update your custom presets. Modules can now be quickly added to or removed from a module group by right-clicking on the group tabs. This new implementation is GUI only – controls and pixel filters still belong to their respective modules and can be properly moved along the pipeline individually using their original, linked, module. Users can add controls from any module to the quick access panel for increased productivity and enhanced ergonomics. This feature provides a new interface to the existing processing modules within a single unified layout. The quick access panel is a replacement for the basic adjustments module and much more. Module Groups and the Quick Access Panel Quick Access Panel This time we are also launching a new version of the lua documentation, here. The user manual is still English-only for the moment, but translations are in progress ( here) and we expect other languages to be available in time for darktable 3.8. Help links within darktable have been updated to point to the new manual and the old version will now be officially discontinued. Thanks to countless hours of work of very dedicated contributors, all of the new features are fully documented in time in the user manual, which is now available in epub format along with the existing online and pdf versions. This is the first of two releases this year and, from here on, we intend to issue two new feature releases each year, around the summer and winter solstices. The darktable team is proud to announce our second summer feature release, darktable 3.6. ![]() Translations of this article: German, French, Spanish ![]()
