I have expressed no opinion on how the image was produced. I merely point out that it is unreasonable to argue that an image that is a "graph" of distance from the body can produce an image delineating the pupil of the eye.
Which means that all of your postings are purely made of straw... because NO ONE has claimed that the Shroud has such resolution... or that pupils are visible on the Shroud.
They eyes are closed... and according to enhanced images they are covered by either coins or potsherds.
