Noel Currer-Briggs on the images
Noel Currer-Briggs, from The Shroud and the Grail: A Modern Quest for the True Grail, describes the Shroud of Turin images:
The figure appears like a shadow on the cloth, and is of a colour not unlike that made by a domestic iron which has scorched the cloth of the ironing board. To those who have never seen a photograph of it, the two figures (front and dorsal) appear head to head, suggesting that the body was laid on one end of the cloth while the remainder was drawn over the head and down to the feet. The face on the frontal image has a mask-like quality and in some degree seems to be detached from the rest of the body: the crossed arms are likewise particularly well defined, and so are the thighs and upper part of the shins. The rest of the body is somewhat blurred.
