This was taken on 12th august at night in a tin mine in cornwall i didnt see it until we got back as battery went flat on my phone. i can see a little boy on the bottom left of the stairs and also looks like there could be some face a little to the right of him.

In 1838 roughly 5,000 children were employed in the metal mines of Cornwall and by 1842 the returns from The First Report show as many as 5,378 children and youth worked in the mines. In 1838 data from 124 tin, copper and lead mines in Cornwall found that 85% employed children. In the 105 mines that employed child labor, children comprised from as little as 2% to as much as 50% of the work force. The employment of children in copper and tin mines in Cornwall began to decline by 1870 (1927, 309).

This is a very good photograph considering it was taken with a mobile phone at 1/16th sec exposure.
There is definitely an image of a human shape on the left of the bottom step. It is more visible if you look at the picture from a distance. View Photo
