Secondo Pia was an Italian lawyer and amateur photographer. He is best known for taking the first photographs of the Shroud of Turin on 28 May 1898 and, when he was developing them, noticing that the photographic negatives showed a positive image of the man in the shroud in addition to a clearer rendition of the image. The image he obtained from the shroud has been approved by the Roman Catholic Church as part of the devotion to the Holy Face of Jesus.

A poster advertising the 1898 exhibition of the shroud in Turin. Secondo Pia's photograph was taken too late to be included in the poster. The image on the poster includes a painted face, not obtained from Pia's photograph.
The Shroud of Turin, also known as the Holy Shroud, is a length of linen cloth that bears a faint image of the front and back of a man. It has been venerated for centuries, especially by members of the Catholic Church, as the actual burial shroud used to wrap the body of Jesus of Nazareth after his crucifixion, and upon which Jesus's bodily image is miraculously imprinted. The human image on the shroud can be discerned more clearly in a black and white photographic negative than in its natural sepia color, an effect discovered in 1898 by Secondo Pia, who produced the first photographs of the shroud. This negative image is associated with a popular Catholic devotion to the Holy Face of Jesus.
