Mainz Central Station (Mainz Hauptbahnhof or just short Mainz Hbf) at night. I stepped out of the Adam & Eden restaurant the other night and I was impressed by the illuminated station.

The above was edited as usual in Darktable. I wanted to let the lights in the windows glow a bit and have them contrast with the otherwise rather dark scene. I did not have a mist filter on my camera, so I attempted to simulate one with Darktable's Diffuse or Sharpen module. In my opinion, the effect of mist filters can quickly destroy an image, it's like emptying an entire bottle of ketchup all at once onto your fries. I was wary of that and attempted to make it subtle. Don't know if this was the way to go.
See my Diffuse or Sharpen mist filter preset over at github.com/bovender/darktable-presets-and-styles.

The screenshot above shows the mask overlay in Darktable. The screenshow below shows the settings of the 'g' channel: I want to exclude dark image areas from the filter effect.

The next screenshot shows the 'hz' channel, which I adjusted to include warmish colors only.

Finally, I applied a large blurring radius so that I can achieve a glowing effect.
I'm not sure yet whether to exclude the moon from the mist filter effect or not.

Here's one of several video tutorials on the Diffuse or Sharpen module by Boris Hajdukovic. He's a master of image editing with Darktable. Highly recommended.
