Inventing a new view to explain filmic curve as a scene -> display range mapping zone by zone for next #darktable. It should make it easier to get.
The clipping alert in #darktable use to be a bit misleading, showing any RGB channel of any pixel out of the [0.1 ; 98] % range. Indeed, such clipped pixels could be the result of overexposure and/or oversaturation, and many users overreacted to this (pic. 1).
We introduce 2 new clipping modes: luminance (for pixels too bright/dark - pic. 2) and saturation (for pixels oversaturated for their luminance, aka out of gamut - pic. 3).
These will make diagnostics more relevant.
