Ray Schneider at Spitzenpopper provides an interesting update:
The Shroud of Turin continues to be an object of great fascination regardless of whether it is the actual burial cloth of Jesus Christ as so many believe or some sort of amazing icon or work of art from the 14th century as the 1988 carbon 14 date seems to suggest it must be. Whichever it is, it is a fascinating and mysterious object.
I have been studying the shroud since the early 1960’s, more seriously in the past 20 years. I am inclined to the view that it is authentic, but there remain plenty of unanswered questions. Perhaps some will be answered using new data. HAL 9000 an organization that specializes in high resolution art photography made a high resolution image of the Da Vinci Last Supper painting and were given an opportunity to apply their wizardry to the Shroud of Turin in January 2008. See a brief video HERE They took a series of over 1600 credit card sized images at high resolution which composited forms the highest resolution image of the Shroud of Turin ever taken.
