M*W: I'm not talking about Nikon or Minolta. What I meant was a prototype projector with internal mirror(s) to project images onto canvas or a wall which was used (illegally) by artists of the day. If I'm not mistaken, I think Leo may have built such a device behind the back of the RCC.
And, oh, BTW, they didn't have one-hour print shops in the 1400s, either. If the Shroud is a work by da Vinci, it was done in the form of a negative, that's why it could have been an experiment on cloth. If there was blood actually found on the Shroud, and if da Vinci was responsible for its creation, he also experimented with cadavers and easily had access to human blood. I don't remember what blood studies they've done or what they found.
interesting idea about the shroud. is it yours, or did you read is somewhere?
im not a believer in the shroud of turin, myself...but i would think that actual blood used to paint it would have decomposed by now?
