I tried the Sigmoid module on the Sunflower Sagas and Solutions play raw. The file is here at 0L0A3314.CR2 (33.3 MB)
The Filmic Version:
0L0A3314_09.CR2.xmp (12.8 KB)
And the Sigmoid version:
0L0A3314_08.CR2.xmp (8.9 KB)
Sigmoid settings were close to out of the box, except I found the RGB Ratio under Color Processing gave the best results:
I found with Sigmoid I was able to bring out glow and contrast to the flower’s petals, which was something I struggled to get with Filmic. As a whole I seem to get brighter colors and contrast when using Sigmoid. This looks very promising.
