Ghost Face Photo

Kimberley Watts photographed this unusual orange blur. We say unusual, because it does not appear that the camera was set to a night time setting that would lengthen the exposure. It was taken with a shutter speed of 1/8 second. It almost looks like half of a face. Is it a ghost?

"While ghost hunting with friends in Auckland, New Zealand, I managed to take an awesome photo of a spirit face. However, it is half a face, but if you look closely you can see facial features. It was a quite still night with no other light source."

Is this half of a ghost face or something else? We do not think this is a product of lengthened exposure, even though the orange anomaly is clearly showing movement. The stones in the background were not blurry at all.
