Do you have any paranormal experineces?

The easiest way to expose these frauds is to challenge them to a neutral lab they have no control over. 

Same with psychics. <-- All of them are frauds and cons.

I knew you'd say that!

 Hang about.

Not always quite as simple as some might think;

One of the most famous photographic frauds was the case of The Cottingley Fairies. It fooled some pretty serious people.Eg the techies at Eastman who declared the photos could not possibly have been faked. Also Sir Arthur Conan Doyle  believed. He even wrote a book about it; "The Coming Of The Fairies'"

Context: During WW1, 1917. Sir Arthur had lost a beloved son, and was desperate to believe. I think that mindset also at least partly explains the massive interest in spiritualism at that time.

Over 50 years later, one of the girls confessed it was a hoax, and showed how they did it. Look at the photos today, and they are obviously fakes.  Everyone has 20/20 hindsight. Detailed pictures are available on Google images.

The Cottingley Fairies appear in a series of five photographs taken by Elsie Wright (1901–1988) and Frances Griffiths (1907–1986), two young cousins who lived in Cottingley, near Bradford in England. In 1917, when the first two photographs were taken, Elsie was 16 years old and Frances was 9. The pictures came to the attention of writer Sir Arthur Conan Doyle, who used them to illustrate an article on fairies he had been commissioned to write for the Christmas 1920 edition of The Strand Magazine. Doyle, as a spiritualist, was enthusiastic about the photographs, and interpreted them as clear and visible evidence of psychic phenomena. Public reaction was mixed; some accepted the images as genuine, others believed that they had been faked.
