At the Shroud of Turin 2025 International Conference & Symposium, Otangelo Grasso presented 3-D Reconstructions of the Shroud of Turin: From Photographic Negatives to AI–Enhanced Forensic Analysis. His presentation traced the extraordinary story of the Shroud through science, history, and technology.
Grasso began with Secondo Pia’s 1898 photographic discovery. For the first time, the Shroud’s faint image was revealed as a photographic negative, showing striking anatomical detail. This breakthrough ignited modern Shroud research and challenged the belief that it could be a medieval forgery.
The next step came in the 1970s, when physicists discovered that the Shroud encodes 3D data. Using the VP-8 image analyzer, brightness values on the linen translated into topographical depth, producing a coherent three-dimensional human form. This was unlike any ordinary photograph or painting.
Finally, Grasso demonstrated how AI tools now reconstruct the Shroud with forensic precision. These reconstructions reveal facial and bodily details that align with Gospel descriptions of Jesus Christ’s Passion. They also provide fresh visual insights into wounds, scourge marks, and burial posture, offering both believers and skeptics a new lens for study.
For Grasso, the Shroud is not simply an artifact but a witness. Its photographic, 3D, and AI dimensions converge to testify to the suffering, death, and Resurrection of Jesus Christ.
