gamut:compréhension comportement fonction

[flyingdd]

Si tu lis l'anglais : https://discuss.pixls.us/t/color-spaces-...pping-wtf/

En particulier : 

What does “out of gamut” mean anyway ?

From a medium space perspective, where white and black are bounded, out of gamut can either mean:

    brighter than display peak-emission (white)
    darker than display peak-density (black)
    too high chroma at current luminance (luminance is valid, but color is too far from achromatic).

Problem being, most gamut alerts won’t make the difference between the 3, so you don’t know if you need to fix the exposure, the black level or the chroma/saturation, or any combination of the 3.

From a reference space perspective, out of gamut only means too high chroma, since we don’t have bounds.

Merci pour les explication théoriques. Concrètement je ne sais pas comment appliquer à mes images les 3 cas en utilisant DT.
    brighter than display peak-emission (white)=> exposition?
    darker than display peak-density (black)=>exposition sur le noir?
    too high chroma at current luminance (luminance is valid, but color is too far from achromatic).=>???
