Interesting in how the face of Jesus changes with some of this new research...
From Shroud of Turin Story - A Guide to the Facts 2005:
"Skeptics and people who believe the Shroud of Turin is the genuine burial shroud of Jesus have always shared one common perception: they thought they knew what the man on the shroud looked like. Now, new computerized image analysis suggests they may be wrong.
Results of this analysis suggest that many characteristics of the images on the shroud are optical illusions caused by random plaid patterns in the cloth. For instance, because of these patterns, the face of the man on the shroud appears gaunt and the nose abnormally long and narrow. By using image enhancement technology to reduce the effect of the variegated patterns, the shape of the face changes significantly. The face takes on a broader look and the nose becomes realistic looking.
Shroud researchers have discovered that these patterns are caused by alternating bands of darker and lighter threads in the cloth. Ancient linen was often manufactured by bleaching the thread in batches before weaving, thus producing nonuniform whiteness in the cloth. "
