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. At typical viewing angles, this image looked much better with all the retained detail as before.Filmic v6 includes a new color science. Notice the graininess, which gave the overall image a busy, grainy look.ĭarktable 3.1, non-local means profiled denoise at 1.4 strength. In order to illustrate this, and without further ado, I took a screenshot of a segment of an image of the Varied Honeyeater I took at the Cairns Esplanade in Queensland (I tried to crop it to be illustrative, and about the right viewing zoom if I were to print or view on screen):ĭarktable 2.4 (2.6 is similar), non-local means profiled denoise at 1.4 strength. It smooths out more noise without losing too much detail and it looks great at "typical viewing distances and zoom levels". Even with the defaults it looks pretty good. I'm glad to report that darktable has a revamped "Profiled Denoise" module.
Secondly, by turning it up to try and get rid of that grainy look, it obliterated a little too much detail.Īnd, as we birders know, high shutter speeds and dark rainforests do not make clean images, even with today's great sensors. First, on a typical viewing distance/zoom of an image, it left a pretty graining "look" to the image. Before darktable 3, I was never satisfied with the basic output for two reasons. Darktable's primary denoise module is called "Profiled Denoise", and uses "profiles" for each camera model to do custom denoising. That gap between the two has narrowed significantly with darktable 3. It was possible to get satisfactory results with some work, but this is the one area where Adobe Lightroom and Aftershot Pro were much easier to use. However, darktable has always had one drawback in my opinion, and that is with denoising.
It's really hard to believe this is an open-source program. First, I'd like to say that darktable is still outstanding. There are obviously a lot of changes from the 2.x series to the 3.x series. In fact, I'm using 3.1 right now on Linux.
Anyway, as another thread has announced, darktable 3.0 is out. I believe the first version I used was around 1.4. I've been a darktable user since about 2015.
