The color smoothing option is the same one used with conventional Bayer sensors. Here are example crops at 200% of the three methods: If even Markesteijn 1-pass is producing artifacts, the 3-pass variant will offer a slight improvement at the cost of twice as much processing time again. Markesteijn 1-pass is a vast improvement over VNG, though it is also twice as slow. It can produce artifacts in fine detail and at sharp edges.Ĭlicking on VNG will show you some higher quality choices: If you are a pixel peeper, or are making large prints, you may not be happy with VNG. For producing images for screen resolution, it should be great. This is a decent quality and relatively fast method. The current default X-Trans demosaicing is done via a VNG demosaic.
The “method” sets how darktable processes what the sensor sees (a mosaic of red, green, and blue) into a color image. For Bayer images, the module looks something like this:įor X-Trans images, you will see a simpler set of options: The demosaic module has different options when you are working with an X-Trans image. There will be more technical information about this processing in a second blog post.
The X-Trans sensor uses an exotic design (unlike the Bayer pattern which is in most cameras), and hence darktable must use different math to process what the sensor records. There are a few differences, though, in the case of the X-Trans sensor. Using darktable with Fujifilm cameras is similar to using it with any other camera’s raw files. Previously, darktable would fail to read RAF-type raw files produced by these cameras.
There is now a development branch of darktable with experimental support for raw files from many recent Fujifilm cameras.
