Description

Not sure if this is a bug. I'm playing with filmic module. In attached RAW file a microscopic change in balance shadows-highlights make a dramatic change in photo. A change by 0.01% in settings makes huge change in photo. Included RAW file, xmp and screenshot (with snapshot)from darktable. For sure this is consequence of previous settings but I don't think it should go like this.

The same change happens on the latitude, which is suspiciously low in your settings.

Try the same with grey = 8 % and latitude = 4 EV. The latitude should be between [25 ; 50] % of the dynamic range, which is 13 EV in your setting.
