I've altered my view.

When you visit the beach for the purpose tanning in the sun, you allow the sun's rays to beam down on the front of your body, and before you burn too much, you turn 180 degrees and the process is repeated on the back of your body.

With that 2-step process in mind, the blood images on the shroud were deposited with radiation hitting the shroud during the resurrection process and that was responsible for the transfer of the blood image onto the cloth.

Jesus' body was emitting light during the resurrection. After the frontal image was produced by His blood, He turned once and the dorsal image was produced, in the same manner. Blood appeared on both sides of the cloth on the outermost fibrils, but did not seep through the entire cloth.

Or Jesus was using the light from the sun, as a source of radiant energy.

I find it would be difficult for, as an example, the sun's radiant light to hit both the front and back of the body of Jesus simultaneously, but Dr. Piczek stated His body was the source of emitted energy, and I, as well thought of this process initially (emission of light, not levitation).

Yet, since the stone was rolled away from the tomb and the soldiers who were on guard were basically unconscious, my feeling is Jesus harnessed the light of the sun to initiate the resurrection process.

Therefore, I propose a two-step reaction involving a levitation. If Jesus is able to levitate, as Dr. Piczek has proposed, He is able to turn once, as well.

The front of His body is subjected to a beam of light from the sun and the frontal image is transferred onto the shroud cloth.

At that point, Jesus turns once, slowly, and the back of his body is submitted to the beam of sunlight and the dorsal image appears on the back of the shroud cloth.

In this manner Jesus is controlling how much energy in the form of photons, as example, is hitting His body.

So, it would be equivalent to your turning over from front to back when you're in the process of receiving a sunburn in the tanning process. You alone control how much light your body is receiving.

In this manner, only the uppermost fibrils on both the back and front of the cloth would be colored with His blood.

And voilà, we have the image on the shroud. Yeah!

This would be what you would call magic, Rachel.
