What
are orbs? Are they the early manifestation of a spirit or do they
have a more rational explanation?
Orbs
are small round shapes of light that vary in size, brightness and
density. With the increasing popularity of digital cameras orbs have
become the most popular photographic anomaly recorded to date. Here
at the CPRS we have seen thousands of photographs captured by ourselves
and submitted by members of the public. We are of the firm opinion
that an extremely high percentage of all orb related photographs are
of a natural origin and not related to spirit.
A
natural explanation.
Most
of the orb photographs out there have been captured with the use of
digital cameras and nearly always with the use of the cameras built
in flash.
Only very rarely are they caught with SLR cameras with high mounted
flash units or in natural daylight conditions with out any the use
of an artificial light source.
The main reasons
for this is the sensitivity of the CCD technology used with digital
cameras and the use of an artificial light source close to the camera
lens. Dust may contain moulds, fibres, and dander from dogs, cats,
and other animals, as well as tiny dust mites. Dust particles close
in to the camera focal range are the normal culprits for most orb
photographs.
When
a digital photograph is taken using the flash any airborne particles
within the focal range and focal angle of the camera lens are illuminated
by the flash and reflected back to the lens. As they are so close
to the lens they are out of focus and therefore appear often as translucent
blobs. The shape of the orb, normally round is due to the particular
aperture type of the camera being used. Virtually every kind of indoor
environment will contain an amount of dust in the air. Any movement
in a building will cause the dust to circulate and carry on the streams
of air caused by natural draughts, air condition units or central
heating.
Dust
itself is does not have a particular reflective quality and therefore
it will be only the odd particle within the cameras focal field and
angle at the time the flash goes off that will be picked up. Moisture
particles are a lot more reflective and by taking photographs outside
at night with flash on a night of high humidity will also give the
appearance of an abundance of orbs on your photographs.
