Contrast threshold

Software RawTherapee
1

RT 5.5 appimage.

  1. The detail tab > sharpening: the contrast threshold runs up to 200.
  2. The detail tab > microcontrast : the contrast threshold runs up to 100.
  3. The transform tab > resize > post resize contrast threshold runs up to 200.

I was told sometime ago that the 3 should be matching/similar (can’t remember who). Does this mean that the microcontrast value should be 1/2 of the others or in the same range when the other values are getting close to 100 or over 100?

Thanks

@heckflosse I believe I have asked about the contrast threshold before (it was regarding demosaicing) but I don’t remember how it works exactly. I know I can look at the code; however, I prefer it to be in words or pseudo code.

I am not very good at separating detailed areas from smoother ones using G’MIC ATM and would like to learn how I can improve. Let’s take [PlayRaw] Sailing Scene @ Garda Lake as an example. The water is very choppy and if you look at some of the entries it is like sandpaper after some tone mapping and sharpening…

@afre So you want to know how it works, not which settings to use in RT for this image, correct?
