Never saw the bilateral filter in shadows and highlights. Makes a big difference!
When you use the gaussian blur you get halo effects with stronger values, with bilateral you got a higher range before halo occurs. In smaller ranges imho it is a personal taste if you use gaussian or bilateral
What is the effect of the negative contrast in the lowpass as a overlay? Increasing the low light regions without attenuating the bright areas?
It’s a part of the ‘subtle but important effect of using shadow color adjustment’. It’s explained in-depth in this video:
in profiled denoise in your modules I see “migrate to the fixed algorithm” but if I add nother instance of the same module I dont have that checkbox.
I don’t see this text, maybe it’s your development version. I use Darktable 2.6.1
looks the color zone saturation settings are the ones that make the trick for why I like the final colors so much. I dont see the hue effect at all.
The red tones in the balloon’s upper part had too much purple in my taste. Therefore I decreased purple saturation and moved the purple to red/orange in the ‘hue’ panel.
Then I realized that the area around the fire has become too greenish so I moved the green a bit towards orange.
looks like you use the tonecurve to reduce the extremely bright shine.
Actually I was trying to get rid of the halo effect above the fire. When you zoom in to the fire and deactivate the tone curve the dark area gets bigger.
Think it came in when I first used the lowpass filter. Didn’t put much time to eliminate that effect completely.
And thanks for your feedback
