Your finding of the second denoise confirms the differences in the screenshot in your first post, too. The fact that you narrowed it down to the second denoise indicates that there's nothing wrong with other modules/settings. However, I tried different formats, bit depth, profiles, intents, with and without high quality resampling etc. Here are my export settings in darktable (not lightroom): The exports start to look different from what I see in darktable when I apply the second denoise (profiled) module (having set mode to "non-local means"). I started with a new copy of the image, so I now have a clean history.

  • The gamut check mode does not show anything, at least not in the mentioned white lines (see screenshot).
  • I tried different export formats using different bit depths.
  • I tried setting “high quality resampling” to “no”.
  • I use AMaZE as demosaic, but also tried PPG and VNG.
  • I export at the same size as the original RAW file.
  • non-local-means), but again, I set the profile as above and increased the patch size to 7. One using chroma preset (wavelets auto) and manually set profile to “DSC-RX100M5A iso 1600”.
  • I use two “denoise (profiled)” instances.

    So it does not seem to be related to the image viewer. When loading the exported JPG back in darktable I can see those noise/grain in darktable, too. Unfortunately I cannot share the whole image or raw file :/ (NOTE: The cyan colors are caused by the gamut check. You can see it in the screenshot I made, for example the structure of the white lines (on the left side you can see darktable and on the right the exported JPG). When I export that image as JPG (Quality 100), view it at 100% and compare the result to the image shown in darktable at 100% I can see that the exported JPG is not as soft as shown in darktable, but noisier/grainier. (I prefer 70% opacity, 15% scale, bottom left, 0,015 y offset)ģ.I used darktable to reduce noise of a high ISO image. Adjust position, size, opacity and so on.Select the name of your watermark file for "marker" (it should be included in the dropdown).

    Select "watermark" ("Wasserzeichen") from "more modules" ("Weitere Module") (this is located at the bottom of the right panel).svg) in the folder ~/.config/darktable/watermarks (for Linux) or C:\Users\\AppData\Local\darktable\watermarks (for Windows).

    Then you can use this style when exporting. You will have to create an image style which applies your logo.
