P: "Intelligent" Grain, preserving Highlight zones
As you compare the grain effect beetwen Lightroom Classic and Silver Efex, you can see that SE is more natural, as the LR grain seems to be plastered on the entire image: the shadows and highlights are equaly recovered with grain while very bright zones shouldn't. It is very visible on B&W pictures.
On a picture if I add film grain effect, I use a Luminance mask and reduce the grain slider to reduce grain impact on the Highlights. Not bad but not quite satisfying.
I wish LR could implement a better film looking grain. Maybe a slider "preserve HL" could be added in the Grain panel, as it exists in the Vignette panel.
Hope this idea helps.
