I tried it once in an old abandoned house when I was in college. I will never touch it again. The pictures I took that night came out very odd. I hadn't had pictures look like that again. I swear, something was following me at work and home after that. I would feel tapping on my shoulder at work but no one was around. I was so creeped out that I went to church and asked someone to release me from whatever spirit was following me.
