|The Story Behind these Photos
These photos were taken as normal documentary photos during our SPI activities.
The above photo is an excellent example of long exposure that is taken in SPI hungry ghost event in year 2004. This photo is showing a double apparitions walking up the staircase. It is a single person however. But the long exposure stretched his image with a trailing effect.
This kind of trailing effect sometimes will distort the subsequent images into scary ghost images. One example is a group of three Taoist priests in SPI experiment doing a ritual to open the Hell Gate during eve of hungry ghost in year 2004.
When look closely, behind the Taoist priests there seem be like apparitions with scary ghost faces. Logically this is due to distortion and blurriness of the moving images. Or really there are ghosts following him when they were trying to open the Hell Gate? If you look carefully, the two apparitions who follow the priest look and dress differently from the priest.
Long exposure is also a culprit of showing a ghost that appears out of nowhere. In the following example, when a person that went into the view of the photo but got out of the view in a short time his image will appear translucent, like a ghost.
Can you see a girl in blue shirt and white short standing in front of the hell gate? Also a boy face appearing on the left of the photo? They are due to long exposure effect.
How can we be sure it is the effect of long exposure or really there is a ghost?
From the above photo, we can check easily via the EXIF Viewer software that the exposure time by which the photo was taken is 25/10 Seconds. That means the shutter opened for 2.5 seconds for receiving the lights into the film.
2.5 seconds you may think is a short period of time. But if you think of human movement, 2.5 seconds is more than enough time for a normal human being to walk in and out of the view.
This usually happens when the subject is of a short distance away from the camera.
One more example I show below is three images of Taoist priest overlapped during a long camera exposure while they were circling rapidly in the ritual of hell gate opening.
Sometimes when taking photos, there may be objects out of view which cast a shadow into the scene. When this happens, people would deem the shadow that appears to come from nowhere to be a ghost.
One very prominent example is during Hungry Ghost month in SPI event year 2004, a demon apparition is captured at the Hell Gate in Haw Par Villa. The demon seems like wearing a robe with a pair of horns on the head.
Next to the demon there is an exclamation mark too (!) Is this a real ghost? However, SPI believe it is a shadow cast from one of the exhibition figurines inside the Ten Courts of Hell.
