Orb (paranormal)
Orbs are considered by some people to be the simplest and most common form of a disembodied spirit. In photography and video, orbs appear to be balls of light with an apparent size ranging from a golfball to a basketball. Orbs sometimes appear to be in motion, leaving a trail behind them.
There are a number of possible causes for orbs in photography and videography.
- Solid orbs – Dry particulate matter such as dust.
- Liquid orbs – Droplets of liquid, usually water, e.g. rain.
- Alleged initial stage of a visible spirit manifestation.
Solid orbsExamples of solid orbs.
A solid orb, or dust orb, is created because a reflective solid airborne particle, such as a dust particle, is situated near the camera lens and outside the Depth of field, in other words out of focus. The pinpoint of light reflected from the dust particle that would be seen if it were at the Hyperfocal distance (the distance from the film or CCD to the object being photographed wherby the object is in focus as accurately as possible) grows into a Circle of confusion with increasing distance from it. |
Liquid OrbsExamples of liquid orbs.
A liquid orb is created because a drop of liquid, most often a rain drop, is situated near the camera lens and outside the Depth of field, in other words out of focus. The pinpoint of light reflected from the drop of liquid that would be seen if it were at the Hyperfocal distance (the distance from the film or CCD to the object being photographed whereby the object is in focus as accurately as possible) grows into a Circle of confusion with increasing distance from it. The appearance of the Circle of confusion is modified by aberrations such as Chromatic aberration or Coma. |
