Paranormal photos: separate the wheat from the chaff.
Although a certain proportion of these photographs remains unexplained, the majority shows a natural or artificial phenomenon, captured under specific conditions and might therefore appears strange and have a ghostly aspect.Whenever possible, I will explain every time how technically these phenomena occur, that are often called “false positive”.A- Objects between camera lens and photographed subjectMany objects, both from natural and artificial origin, and combined with either inadequate or unintentional camera setting , may take appearances making them completely unrecognizable.
In most cases, the operator does not see the object(s) that is (are) the source of this confusion because they is (are) either too small and / or far away (orbs, …) or too fleeting (rods, …).
It is also noteworthy that almost all these photographs are taken at night with flash, underlining the role of its use in the creation of these artifacts that otherwise would not have been visible (mists, spider webs, .. .)
1- Camera strap
Yes, you read it right! Camera strap is one of the most common cause of “Vortex creation” confusion!
Accidentally left very close in front of the camera lens, the strap appeared as white spiral ‘shafts of light’ when illuminated by the camera flash.
Almost all camera straps are tightly woven together using a nylon fabric of sorts. So how in the hell do people not notice a camera strap in front of the lens?
Quite simply, given the conditions in which most of these photos are captured (aka the dark), most people are focused on what is going on past the camera, not what is happening with the camera themselves
There are plenty of examples around the net:
Another common source for “Vortex” is hair.
Hair contributes to a great number of anomalies that are floating around the paranormal field. Surprisingly, many people still refuse to accept that hair was the culprit. Hair will often appear translucent and may even seem brighter and fade out and disappear on each end.
This will depend on the angle of the hair in correspondence to the cameras flash.
3- Mist, smoke, steam and condensation
Mists (some people think they resemble ectoplasm) are common on anomalous photographs. Such mists have, like orbs, become much more common since the advent of digital cameras.
Like orbs, their cause is not usually noticed at the time the photograph is taken. Many such photos are taken in allegedly haunted places.
The origin of the mists is probably mostly the photographer’s breath on a cold night. It is generally night because the mists need a dark background to show up well (and not be seen by the photographer) and cold for obvious reasons.
A small number of cases may be caused by the photographer smoking and then forgetting about it!
The reason why the mists are on the photo but not seen at the time is that they are in the ‘orb zone’, where the flash produces intense, if brief, illumination.
Mists are the most common cause of pareidolia in “paranormal” occurrences; their aspect is open to many interpretations:
4- Bugs, moths, flies…
Bugs are a variable that cannot always be discounted. They are also extremely difficult to see in the dark, if you can see them at all. Flashlights and other sources of illumination attract these nighttime flying insects.
Round insect orbs are rare. Insect orbs are also very brilliantly white frequently overexposing the image. There extreme brilliancy is due to the insect’s relative large physical size as compared to dust or lint.
This larger size provides more area to reflect the light from the flash to the camera lens. There images are typically smaller then other orb types due to the fact that further out insects will show up in the picture.
5- Spiders webs…
Spiders webs collect water droplets on knots in the silk spindle or in single strand in a damp or foggy atmosphere. Then, especially in the morning, bright pearl-like water drops hang on thin spider silk after a fog.
At night, the camera is not able to properly focused in such thin thread, thus the odd aspect we can see in the examples below, when the flash fire. Sometimes, there’s only a few water droplets and the rest of the spider web cannot be seen by the camera eye…
Rods are nowadays a well-known phenomenon that is fully explained and widely admit as a phenomenon involving both a flying insect and specific settings of the camera.
The experiment below explain in a very understandable way how it works:
Like Rods, Orbs are now fully explained and widely admit to be only unfocused dust illuminated by the camera flash.
There is a huge amount of variety of orbs, including colored, moving, partials, etc… I’ll not detailled here how each of them are created, however you’ll find thorough explanations here with lots of examples here as well.
The “orb zone”
When an object is too close to a lens to be in focus, it looks fuzzy. However, it becomes fuzzy in a quite specific way. It turns into a series of overlapping circular blobs of light called ‘circles of confusion’.
These can appear quite sharp (see top photo) but they are actually a representation of a single tiny point (a highlight) on the complete object (which, overall, then looks fuzzy and out of focus).
You can often see this ‘orbing’ effect in pictures where there is a portion (particularly in the foreground) that is badly out of focus.
Very small objects, like dust particles or small water droplets, produce just a single circle of confusion (or orb). This effect can occur anywhere but is often only noticed when it occurs at somewhere significant, like a haunted house.
Digital cameras have lenses with a much greater depth of field than film cameras. This means that the nearest point to the camera that is in focus is a lot closer. It also brings the ‘just out of focus’ area (‘orb zone’) closer as well.
The ‘orb zone’ is so close that it is intensely illuminated by the flash. The intensity of the flash increases according to an inverse square law with decreasing distance.
Indeed, if the subject of your photograph is at a distance of 5m, a particle of dust at 5cm from the camera receives approximately 10,000 times greater light intensity!
This creates an ‘orb zone’ in digital cameras where the light intensity is sufficient to illuminate the faint out-of-focus bits of dust, which appear as circles of confusion (or ‘orbs’).
The graph shows flash illumination diminishing with distance (to right).
O = too out of focus to be visible even with flash
Z = (orb zone) out of focus but visible due to high flash intensity
B = out of focus but invisible because flash not intense enough
F = in focus and visible
In a film camera, all the zones move further out and the ‘orb zone’ generally vanishes because there is insufficient flash intensity at the increased distance.
As digital cameras get larger CCDs (not just megapixels but physically), their lenses get decreasing depth of field. This means that the problems of orbs and strange mists should gradually vanish. No more spoiled pictures!
B- Camera tricks
1- Double exposure
To create a ghost effect, place the subject in front of a background that is of average brightness. Take an exposure.
Then move the subject out of the way and expose again, maintaining the registration of the image with that of the first exposure. The will give a ghost-like appearance to the subject because the background is visible through the subject.
Note that this method does not work with dark backgrounds because the second exposure will not be bright enough to be seen through the subject and the subject will look very normal, unless it moves between the two shoots, the result being then to have twice the subject in different posture:
Note that in the above picture, there are two combined results (the woman that appears twice and the blue light streak) of both the double exposure and the camera that moved between the two exposure
2- Light trails
A light trail is seen to emerge from a light source (though the light source could be off the side of the frame).
It happens when you take a flash photograph of a dark scene which includes a light source (such as a torch) while moving the camera. The flash freezes the dark background but the light source leaves a trail because the camera is moving and the shutter is still open.
While the flash typically takes thousandths of a second, the shutter may stay open for hundredths, or even tenths, of a second. The long relatively long shutter exposure is known as the ‘flash synchronization shutter speed’. Your camera manual may explain how to adjust it.
Interestingly, there are some examples where you can see that the light trail is made of short dotted lines.
The above photo is a bus passing with its headlights on on the street.
The lights of the bus are incandescent bulbs with a tungsten filament, powered by alternating current, and heated to 3000°C. It does not have time to cool down to show the slightest flicker when switching repetitive current alternative to 0V. In fact, the trails are continuous and captured by the camera lens as it.
Street lights use discharge lamps with sodium vapor (yellow / orange) or mercury vapor (white / blue) which are produced in electric arcs in the middle of a gas, which ionizes and produces the light. This is not a continuous process. These discharges are at high frequency to produce an illusion of continuity.
It’s the same principle in the movies. I suspect this frequency to be of 50Hz, that of the electric current distribution in Europe (In UK, I think it is 60Hz).
This phenomenon is usually invisible to the naked eye, but not for the cameras …
Beware of the mirrors when taking a photo! They are often the cause of unwanted reflections…

Another example with a shadow reflection on the mirror:
This picture would seem to show a shadow figure in the mirror.
But it’s just the reflection of LIPI Lead Investigator Moshin Marghoob (on the bed).
Pareidolia refers to the human tendency to see faces and other patterns in noise.
It can be for fun, like seeing patterns in clouds, but sometimes people start thinking that the things they are seeing are really there.
It applies for many paranormal photos, like for example:
Unfortunately, some people have the need to deceive others. There are many ways to create fakes and, as this is not the purpose here, I’ll not expose how paranormal fakes can be created.
This is more than ever true since technology help forgers:
I’ll content myself to show such examples, taken from ATS threads:
