Famous Ghost Photograph: Newby Church

Reverend K.F. Lord took this picture of the altar of his church in North Yorkshire, England, in 1963. When the picture was developed he noticed what appears to be a shrouded figure standing in the picture.

According to reports on the Internet, the photo and negative was thoroughly examined by experts and proven not to be a double exposure nor was there any signs of trickery.

Why this picture could be real:

Credible photographer (he is a reverend).
Almost too fake looking not to be real. I think a fake would look "better" than this.
The site was not reported to be haunted when the picture was taken. Usually, people pick a location that is known to be haunted because it makes the picture more believable.

Why this picture could be fake:

People have calculated the image to be nine feet tall. Ghosts do not usually expand, but appear at their normal height. It seems the extra height could be the result of a miscalculation.
The image is consistently translucent. The more realistic ghost photographs tend to show an image that is almost solid in some places and translucent in others. This image is equally translucent all the way through, which suggests a double exposure.
The picture seems to show a "robed monk." Newby Church was not built until 1870 and was never home to any monks.

I'm not saying that this image is or is not real. I just don't see enough here to say it is a ghost. More research on the history of the photograph is necessary before I make a final conclusion.
