Taking the image from this post I feel it does a nice job… These sorts of images have often been hard to manage. With the sigmoid curve module the default is to preserve the hue but there is a slider to dial this back…in doing so with this image you can go from 100% which is a bit more of the reddish hue at least perceptually and slide along to zero where you get the yellow…in between you can hit a nice mix. The second option with no slider seems a bit like filmic v6 set to no or luminance… but this simple slider to cover a nice range of yellows to redder sky lets the user land on what they like…maybe not accurate but then we have filmic and all its nuances as well is this simple one doesn’t meet what is needed…
So simply taking this image and doing an auto exposure for 50% which lands around 1.8 EV … I get this by default…
At 50% preserved
And at 0 you can see yellow
I think I stopped around 35-50 % on my screen for a nice balance or pleasing image to my eye…
Tweaking the skew and zeroing preservation as in the provided preset…really brings up the yellow…
So it will be interesting as more people try it on their images giving them issues with the current tools and see how it compares…
