IMHO, since I believe that this is a person and not a spirit; let's say that the camera's shutter speed were set to say 1/30 of a second. It doesn't look like there was any flash used for this particular photo. If it had been used, most flashes on auto sync will provide 1/60 of a second. If this was a person, the 1/60 of a second could stop the movement of the figure, depending on how fast the subject moved if it were flesh and blood. Since the camera's shutter was set for a slower shutter speed/no flash, any movement by the subject would be affected. It also doesn't look like a shadow; looks more like a person dressed in black as there appears to be separation of apparel material just below the waste level.
Now, as some know on this forum, I have taken photos with long exposures [no flash, sometimes even beyond 30 seconds] and have gotten nearly 3 dimensional looking spirits on the photos with no movement whatsoever.
So, my opinion is based on experience in the field and the results thereof. But, I could still be wrong with this photo of course. Spirits can expose themselves in different ways I believe; so I don't believe that there are any set of rules. Just my 2 cents again.
