set your flash to under expose by about 1/2 to 2 stops. With the slow shutter and underexposed flash you’ll now get two images. One captured by the slow shutter and ambiant light, and the other created by the stop motion of the flash. The slow shutter image is your ghost.
Come back tomorrow to see real examples of ghosts in photos – and a very spooky shot of my family showing the ghost of one of my ancestors (really!).
see ya tomorrow (scary stuff!)
