Good luck!... try taking photos with a digital camera... even at night and with flash. Some people will tell you that it is dust spots, but some pictures will have none and others will have many. Also, how does one explain the faces? Sometimes there are no EVP's. Some faces will be without an orb... just there on the photo. You need to view the photo on a computer and enlarge it and then scroll inch by inch. You'll be surprised by what you can get!

The experiment with a flashlight (mag lites with a twist on feature) that you set to almost on and then ask them to respond by making the flashlight turn on is a fascinating experience.
