New Sigmoid Scene to Display mapping

[ariznaf (Fernando)]

Well here is the test I was asked for:

Processing skies with clipped channels in Darktable filmic/sigmoid

Well, this test raw is originated by this discussion about sigmoid and filmic tonal mapping. There is people like me that says filmic is difficult to fight when you have skies that are over exposed and you want to get them back to a more natural and interesting look, and other tone mapping tool like sigmoid would be interesting. So here am I trying to provide an example with overexposed sky (and some other part of the photo) that wanted to turn in a more natural look. Not a good or interestin…

Probably not the best testing photo you can get (the other of the bridge would be more interesting) but one that presents clipped highlights and a dull overexposed sky.

I have processed it with sigmoid, but I have an old version (DT 3.3).

The results using color calibration to darken sky I think are quite better than what I was getting previously.

Thanks to all.
