False and real 'ghost pictures'

This week, we've conducted several tests to create 'fake' ghost photos. Some of the pictures were startling, while others confirmed what we'd already asserted.

False ghost pictures - Hair tests - These look a lot like some 'vortex' pictures.

This is confirmed by even more photos, at More fake ghost pictures with hair.

False ghost orbs - Dirt and dust - This test confirmed that dust and dirt aren't such significant factors in 'ghost orb' photos.

False ghost orbs - Sprinkler experiments - This is an unlikely source of false orbs, but we had to check it out, just in case. We learned that lights are more of a factor than water.

False ghost orbs - Flour experiment - We'd hoped for more interesting results. Instead, we learned that it can be very difficult to fake orbs with particulate.
