![]() I use Linux, and don't read articles on software that won't run on my machine. I have a Nikon, so I don't read Fuji/Sony/Canon etc. I don't get all those people who come here to say 'no thanks, I use ' and 'I have no time to learn all this geeky stuff' or 'I tried it and it's not for me'. If you would like to give darktable 4.0.0 a try but don't know where to start, there's a very detailed user manual available here. At that link, you can also download the software's source code. For the full details, visit darktable.ĭarktable 4.0.0 is available now for Linux, macOS and Windows. Plus, there are many new bug fixes in the latest update. ![]() There are many more other changes, including a color glossary, new contrast parameters, a new 'collection filters' module, improved search, improved export options, improved shortcuts when using sliders, a new raw exposure function, and more. The app's performance and OpenCL settings have been optimized, so performance is more tunable by the user and should be improved overall. The default theme is now Elegant Gray, which is the recommended choice of the darktable team. Superfluous sections have been removed in 'crop' and 'white balance' tools. The vignetting module has been split into two sections. Collapsible sections within modules have been redesigned to improve functionality, plus channel mixer RGB, exposure and color calibration modules include new collapsible sections. Padding, margins, color, contrast, alignment and icons have been reworked throughout the application. The user interface has been completely revamped to improve the overall look and consistency. ![]() It will make the saturation control in color balance RGB better behaved.' You can learn a bit more about the Helmholtz-Kohlraush effect in the latter half of the video below. ![]() What's this actually mean? Darktable UCS 22 ' uses a brightness-saturation scheme that compensates for the Helmholtz-Kohlraush effect (accounting for the contribution of colorfulness in perceived brightness) and allows an efficient gamut-mapping against pipeline RGB at a constant brightness. It's a perceptually uniform color space built using psychoperceptual experimental data that was gathered for artistic saturation changes. This method is only available for images captured with a Bayer sensor, so Fujifilm X-Trans users are out of luck here.ĭarktable 4 introduces the darktable Uniform Color Space 2022 (darktable UCS 22). This uses a 'multi-scale wavelet scheme to extract valid details from non-clipped RGB channel(s)' and 'propagates the color gradients from neighboring valid regions using edge-aware color diffusion.' The team writes that this feature promises to limit color bleeding through edges, such as green leaves bleeding color into a reconstructed blue sky. Within the 'highlight reconstruction' module is a new 'guided Laplacian' method. This allows for more saturated colors, notably in blue skies.' Darktable 4.0.0 now includes a 'fully-sanitized color pipeline' from input (color calibration), creative changes (color balance RGB) and through to output (filmic v6). Darktable writes, 'This change removes the mandatory desaturation close to medium white and black and replaces it with a true gamut mapping against the output (or export) color space.
