An intrepid photographer went to a haunted castle
determined to get a picture of a ghost which was said to
appear only once in a hundred years. Not wanting to
frighten off the ghost, the photographer sat in the dark
until midnight when the apparition became visible. The
ghost turned out to be friendly and consented to pose for
one snapshot. The happy photographer popped a bulb into
his camera and took the picture. After dashing into his
studio, the photographer developed the negative and
groaned. It was underexposed and completely blank. The
spirit was willing, but the flash was weak.
