Surely, someone in Turin has seen the data and decided to not make it public for some reason.
On the Haltadefinizione website we read:
Haltadefinizione® was in charge of the shooting of the cloth of the Shroud between January 22nd and 23rd 2008.
. . . Haltadefinizione® was authorized to acquire high definition (HD) digital images of the Shroud. These HD images represent a milestone in the history of the Shroud. During the shooting of the Shroud, the entire surface of the cloth was captured for the first time using advanced HD photographic techniques. . . .
The image reached an unprecedented optical resolution not visible to the naked eye, allowing clearly to distinguish the individual elements that compose the cloth: elements of a diameter of a few hundredths of a millimeter.
[ . . .]
. . . 1649 photographs were taken, each of which represents the area of the size of a business card, creating a single image of 12 billion points stored in one file of 72 Gigabytes, equal to the contents of 16 DVDs.
In order to reproduce the entire image at its maximum enlargement, a humongous cloth would be needed, 68 meters wide and 18 high. . . .
That is 223 feet long by 60 feet wide. That is more than 2/3 of the length of an American football field, not counting the end zones. Does that not give us an idea of how valuable this photographic data is?
But as Mario Latendresse points out in a comment:
This photo file has never been shown publicly (at the resolution taken), not even on the app Shroud 2.0, although many people think so. What is on Shroud 2.0 is a lower resolution.
And Colin Berry points out:
[The] Haltadefinizione site . . . [tells us] “HD digital photography by Haltadefinizione® is an indispensable tool for researchers who wish to access anytime to unique images of the Shroud and process them in real time”
. . . It’s described as an “indispensable tool for researchers”, as indeed it probably is. But is it available to researchers? If so, then why no details on the Halta site about how to gain access, beyond those relating to the feeble Shroud 2.0 (a damp squib if ever there was).?
Why is this so? Requiring 16 DVDs to hold it, is the file too big? Down with the flu, I downloaded half that many DVDs from Amazon.com in a couple of hours. On the bookcase, the entire Inspector Morse television series contains 18 DVDs in a single box. Breaking Bad, 21.
Think about some of the questions that we might be able to answer if we could see the Haltadefinizione images. Many people went to a lot of trouble to create these high-HD images. Surely, someone in Turin has seen the data and decided to not make it public for some reason.
