My girlfriend and I at the time took some photos at a know haunted spot back in 2008. Two pictures developed where you could see two obvious distinct ghost images in a rear view mirror and a backseat window. These photos were definitely not manipulated in any form. As years went it on and I immersed myself in physics theories, it always fascinated me to think maybe somehow this could be tied with capturing light. It seems as if all ghostly known images are roughly from the 19th and early 20th century. We never see any images of colonial settlers, Indians, Vikings, pilgrims, Egyptians, or anything relative to a time more than 200 years ago. Obviously some haunted places are said to be possessed by things older than this but I'm more connecting images by cameras. The first known photograph was taken around 1826, with this being said can we somehow link past photos taken with images being brought back? Maybe somehow and older pic was taken in that exact location which linked future picture taken at that location. Is there any known physics that could back this up or should i take another path in thinking about the topic? Ideas you guys have thought about would be interesting as well!
