Black Image with CurveRGB + FilmicRGB + LocalContrast [SOLVED]

Hi everybody,

this week end i tried to process photos using a linear RGB workflow.
I noticed that when I turn on Curve RGB + Filmic RGB + Local Contrast the image in the darkroom turns completely black. In order to use the three modules together i have to shift Curve RGB after Filmic RGB in the pipeline.

I just wanted to report this behaviour in case this is a bug. I’m using darktable on windows 8.1 but I will test it also on window 10

I can provide you some examples later in the day.

it’s already known and fixed in current master. For an explanation see:

Workaround: in Filmic rgb set preserve chrominance to luminanceY or max RGB or no
