MS paint...just have a look...
Lenny, Lenny, Lenny. . .
hahaha. I just had a diabolical thought. . .
If I were doing it I would take the original, mess with it a bit to scuff the surface. Make that my starting point. From that fabulous finish, I would deconstruct the pic, painting over everything in roughly the corresponding paint in the corresponding places, simplifying as I went all the way back to a white canvas.
And when all was taken to a white canvas, I would reverse the video footage and put music playing forward normally over it, and you have a David Copperfield illusion going of being able to paint like Leonardo.
That's if I were doing it the easy way.
Course, if this were the Italian Renaissance, I would get some really hot shot artist guys in my studio to do the work and then just sign my name to it. . .
. . . if it were the Italian Renaissance that is, the Flemmish, the Spanish, English, The Professor and Mary Ann, etc. . .
But there probably are folks out there who can do it. I've seen some pretty amazing artists.
Thank you , Mr. Hanzz!
That's just awesome!
