Negative and Positive Phenomenon

© COPYRIGHT 1978 BARRIE M. SCHWORTZ
The image on the left is how the
face appears on the Shroud. The image on the right is a photographic
negative. Since the image on the right looks like a positive image, we can be
quite certain that the image on the Shroud is a negative image.
This property was discovered by Secondo Pia, in 1898, when he examined the negative of a photograph
of the Shroud in his darkroom. Pia was the first person to ever photograph the
Shroud.
What me mean when we say negative image is that lighter and darker tones
are reversed. For instance,
the tip of the nose on the Shroud is dark but when reversed, it is
almost white.
It is this visual characteristic of the Shroud's
image that has led some to believe that the image is a form of medieval
proto-photograph. But the argument fails on two specific point. Chemical
analysis clearly rules out the light sensitive chemical required for a
photograph and image analysis shows that the highlights and lowlights
are not produced by reflected light.

The
scientific study of the Turin shroud is like a microcosm of the
scientific search for God: it does more to inflame any debate than
settle it.”
And yet, the shroud is a remarkable artefact, one of the few religious
relics to have a justifiably mythical status.
It is
simply not known how the ghostly image of a serene, bearded man was
made.”

Nature, January 2005
Nature, that most prestigious of scientific journals, that once had
bragging rights to claim that the Shroud was fake, responding to new,
peer-reviewed studies that discredit the carbon 14 dating and show that
the Shroud could be authentic.
WHAT WE KNOW IN 2005
- The Shroud of Turin is certainly
much older than the now discredited radiocarbon date of 1260-1390.
It is at least twice as old and it could be 2000
years old.
FACTS
- Though no one knows how
it was made, the image is a selective caramel-like darkening of an otherwise
clear coating of starch fractions and various saccharides.
FACTS
- The blood is real blood.
FACTS
- Much of what we think we see in the
image is an optical illusion.
