When I was out and about today, a lady came up to me and started talking to me about some photos she was taking using the Oldfield Filter. It was a filter you put in front of a regular 35 mm camera. From the blurb on the youtube link below it says
"The Oldfield Filter is also called "Spiritual Photonic Photography" it is a filter that works of the the theory that light moves at different speeds and also spirals. It breaks light up into its base colors, These frequencies then interact with invisible energy fields to show pictures and patterns that are invisible to the naked eye. This filter has been used with great success in paranormal investigation. As entities show up clearly."

Just wondered if anyone had come across this at all, has one, and used it? Was thinking it could be used to take aura photographs?
