Mainz Central Station (Mainz Hauptbahnhof or just short Mainz Hbf) at night. I stepped
|
|
out of the [Adam & Eden][ae] 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][gh].

|
|
|
|
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.
