Overlay white background transparency

[NN636664877012671982UL]

Hi all,

Anyone know how can I use a white background draw (sketch on a paper scanned) in overlay, but to see only the sketch and ignore the white paper (white colour).

Could you use the Luma Mask functionality to essentially mask out the white paper, just leaving your drawn sketch visible?

There is a workaround. I can open my draw with Photoshop, then apply a mask on white (convert to black and white, levels to have high contrast) then save PNG with mask (as transparency) and use it in Capture One. Just it is a long process and maybe is not easy to people who does not handle PS so good.
So I thought maybe in the future we can have a mask out white button in Capture One.
