IMHO the bare composition is easy for painters to put on to paper. There are lots of 4 years old drummers , pianists and lots of incredible talented painters in this world today to past. I think if you give that device to someone , he could put only the traces. The trick is the grades , light on the paper. If you are not a very very good painter , you could not put the grades. And the colors and their layers. You must be very experienced , lot of teaching from the other masters to do that. And color balance , contrast and 3 d relief.
I bet tim or other guy painted their versions from single mixed color , not from may be 7 different layers.
May be someone gave the device to vermeer and he liked to use that , but I bet it helps for %1.
Art people or investors are not idiot , you dont give 50 ,100,200 million dollars because it looks good.
It must have a place in history and the process and it must be hard to master.
Look at picasso paintings , few lines only but you know he did the other way also and walked a long way.
