i think commen for people who a used to colorgrading techniques 
I am pleased with the fact that we have several methodes in DxO-PL now to create a B&W or B&W and colored objects.
- The mask invert is a major step in controling isolated parts of the image not only color but also other things asblur
The HSL tool is that powerfull that a non trained person in colorgrading can find the blunt and easy visual seen adjustments but not the careful adjusted colortints/HUE corrections it also can deliver.
This tool has enough for a tutorial on its own.
replacing color, enhancing a colorrange, create a post layed colorfilter by white channel and normal you don’t have in white channel luminance and uniformity but (if i round the color channel full round you still have the three sat/lum/uniform sliders active, three sliders and three controls as in huebandwidt (channel) feathering of overlapping channels. endless playing time
The old HSL i didn’t catches it’s use for me it didn’t pulled me in using it but the new is fun to use and you can go wild in changing colors and or saturation/lumination/uniformity and that 8 times plus a White full hue band channel. To master this tool in it’s full capacity some tutorial and guidens is appreciated. HINT hint hint.
And Silver effex and style toning and filmpack W&B’s
