FICTIONAL REPORT: Pendle Hill, New South Wales.Twelve witnesses.
Shot in the early evening from a back garden. Other witnesses were gathered in the street at the front of the house. Although the video shows lights only, some witnesses claim they could see a solid object. This was disputed by others. (NOTE: this is second-hand information from our witness.) Also note that when the lights appear to turn into diamond-shapes, this is an artefact of the video-camera going out-of focus.
REALITY: When a video camera goes out-of-focus while pointed at a light, it often betrays iris artefacts such as diamonds. This effect can be simulated, and lends much more realism to a shot than a simple blur, although it takes a lot of computer power to render. Many observers claimed this one was 'impossible to fake'. The lights are streetlights, pasted in and animated.
