![]() ![]() 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. It is important to note that, what 99% of software calls “saturation” is actually a setting that alters chroma (colorfulness irrespective of lightness). This setting ‘honors the Munsell and CIE (International Commission on Illumination) definition of saturation: colorfulness relative to lightness. This can be used to dampen colors before adjusting the balance, to make difficult images easier to process. The Color balance RGB module also includes what darktable calls real saturation. Changes the hue, saturation, and lightness (HSL) of specific colors in darktable using the Color Zones module It's a super useful tool to adjust the colors. A saturation correction applied before the color balance. It also uses luminance masks to split the image into shadows, highlights, and midtones, allowing each to be color-graded separately. All saturation-related 'changes' comparing to old behavior are expected, as the old behavior changed saturation in a non-uniform way across the tones. You can also combine the color to create secondary and tertiary colors, for example, Orange (Yellow + Red). The same for Magenta/Green and Yellow/Blue. This is because Cyan is the opposite color to Red in the RGB color wheel. The module prevents users from pushing colors outside of the valid working range when editing. You can insert Cyan, Magenta and Yellow pixels by decreasing the Red, Green and Blue channels. colors, sharpening, and add a vignette for a professional looking result. This uses the same basic algorithm that the filmic rgb module uses for tone mapping (which preserves RGB ratios) and for mid-tones saturation (which massages them). Im here to introduce you to one of the most powerful pieces of RAW processing. The Color balance RGB module introduces several innovations to improve color editing. The brightness and colorfulness (color saturation) of pixels in an image can also be adjusted based on the R, G and B input channels. 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. A further improvement is the ability to add and remove modules from a module group quickly.ĭarktable writes, ‘Now that scene-referred image processing is virtually feature-complete in darktable 3.6, scene-referred is now the default workflow. 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 the app. ![]()
