According to a researcher of Telekinesis, there are two types of world around us. One is physical world in which we are living and the another is counter world which is the mirror of our physical world. If there is counter world, I think ghost stays in counter world. So we can't take the photo of ghost.
Remember that this article does not advocate the existence of ghost. I also do not support or oppose the existence of counter world. Because I have not researched on it. This article is written only in a reference to the research done by a foreign researcher of Telekinesis.
