I recently received a letter from a Shroud skeptic defending the work of Walter McCrone that prompted me to draft a reply (which I will include in our next website update in early June). While writing my response, I referenced a paper that we published in 2000 by David Ford which independently evaluated and summarized all the available data titled, The Shroud of Turin’s ‘Blood’ Images: Blood, or Paint? A History of Science Inquiry. The paper is worth reviewing again and can be found at http://www.shroud.com/pdfs/ford1.pdf, in case you missed it.
