I really enjoy these old ghostly photos mainly due to it being less likely, faked, by modern technology and software tools. I'm not saying that they therefore can not be explained by some other logical reasoning (printing glitches/camera malfunction etc), but they do have a sense of "authenticity" about them.
I did some research about the famous Hooded monk spectre of Newby Church and found bits and pieces of information.
Apparently the photo was taken in the 1960's by Reverend K. F. Lord at Newby Church in North Yorkshire, England. He claimed that he saw nothing unusual in the church on that day, and that the photo was merely a snapshot of the altar. Only after developing the photograph did they see the image of what is supposedly, a hooded monk.
The church has no reported history of being haunted and was built in the 1870's. The robe the monk was wearing is called a cowl
and you can read more about it here
. Unfortunately no one could get their hands on the negatives to see if the image has been tampered with, although many experts say the image as we see it here, was not. Some analysts reckon the monk was around 9 feet | 3 meters tall...
Another one I enjoy is that of the "Brown Lady of Raynham Hall"
The Brown Lady of Raynham Hall is a ghost, which reportedly haunts Raynham Hall in Norfolk. It became one of the most famous hauntings in Great Britain when the image of the 'Brown Lady' was captured by photographers from Country Life
magazine who were photographing the staircase in 1936, where it would become one of the most famous paranormal photographs of all time. The "Brown Lady" is so named because of the brown brocade dress it is claimed she wears.
According to legend, the "Brown Lady of Raynham Hall" is the ghost of Lady Dorothy Walpole (1686–1726). The story says that when Townshend discovered that his wife had committed adultery with Lord Wharton he punished her by locking her in her rooms in the family home, Raynham Hall. According to Mary Wortley Montagu, Dorothy was in fact entrapped by the Countess of Wharton. She invited Dorothy over to stay for a few days knowing that her husband would never allow her to leave it, not even to see her children. She remained at Raynham Hall until her death in 1726 from smallpox.
The first recorded sighting of the ghost, made by Lucia C. Stone concerning a gathering at Raynham Hall at Christmas 1835.
