IS LEONARDO DA VINCI'S FACE ON THE SHROUD OF TURIN?

If this was Leonardo's doing,

(1) where did he get the rare cloth from (no copies in Europe during his time) exhibiting a herringbone twist pattern?

(2) why did he contaminate it with over thirty variety of plant pollens, a lot of them originating from Palestine?

(3) how did he manage to place an imprint on the cloth AFTER spiking it with blood? Seems absurd. There is no image under the blood areas.  A smart guy like Leonardo would have done the reverse. Yet, the blood flow patterns closely match the wounds that are on display. This is more than remarkable.

(4) If Leonardo was pioneering a proto-photographic method, how come we don't find other copies like that of the shroud's or similar creations showing 3D coding in the pictures?

There are ton of other questions. You get the "picture."
